Rated 4 out of 5 by from pretty decent ampUsed this Amp with The ADX shaker is pretty powerful alone, I like the design of the heat sink .I have this shaker mounted under my Futon Couch, its powerful enough to shake both the left side and the right side of the couch... it is mounted in the middle. I have it connected to a 70w DNY subwoofer Amp, that I also brought from parts express. I usded an 18 Gauge speaker wire to connect to the AMPS output located on the back side of he amp.. Then I used a male RCA subwoofer cable , and connected it to the left Mono out on the amp, and connected the other end to the Y splitter female connect on the back of the recover on the sub-woofer out.. Make sure in the recover cross over setting's are set to 40 HRZ, by default mines where set to 180. , also on the recover settings increase the subwoofer output , you will feel more shaking from the shaker this way..... also by doing this you can dail down the subwoofer valume on the back of the subwoofer so you only feel the shaking and not everyone else

Rated 5 out of 5 by from Perfect amp to run bass transducersI purchased this amp to run two bass transducers (Aura AST-2B-4 Pro Bass Shaker also purchased from Parts Express) wired in series. This does a great job. I installed all of these pieces into a couch that has a pull out bed in it. It all fit perfectly. I installed the amp into the back of the couch. The instructions specifically say not to do this, so I am doing this at my own risk. My only complaint is that to get the desired bass response, I have to run the amp at a higher "volume" than I would like. Of course, I could increase the subwoofer output levels from the AVR, but then I would have to reduce my sub volume. The end result is that it runs a bit hotter than I would like.

Rated 5 out of 5 by from Good Amplifier at its power levelI was quite pleased to find that the amplifier is fully enclosed in a plastic case.I was concerned that 70 watts would be insufficient for my application, and I am getting good bass in a 15x20 foot room.

Rated 3 out of 5 by from Worked Great Until It Didn'tI bought the Dayton 70Watt amp to power my Aura Bass Shakers. The effect was awesome until after 6 months it stopped working. I tried everything to revive it and no luck. The only thing I can think of is that I didn't plug it into a power strip and I left it on auto all the time. I talked to Parts Express and they said they would replace it. I think I'm going to get a power strip and turn it off when it's not in use and see if I can get it to last longer.

Rated 5 out of 5 by from Economical Replacement for Blown TSS-450 amp.I purchased an Infinity TSS-450 surround system at a bargain price only to find the amp on the subwoofer was blown. After determining the main board was scorched and beyond repair I decided to try a Dayton Plate Amp. I took a chance on the 70 amp versus the 100 amp version based on some of the reviews and it was a wise choice. I left the original amps plastic "tub" in place and clipped off the original speaker wires to extend the too short Dayton wires. The Dayton Plate amp just fit into the tub of the original amp and by slightly angling the side screws I was able to secure all but the bottom two screws leaving about a 1 inch gap which I figure will aid cooling. The amp is still sealed from the rest of the speaker and the original geometry of the speaker is maintained. After hooking it up to the SUB output on my receiver I turned it on and was amazed that I only had to open the gain less than 20% to get all the bass I needed to fill the lower end of my system. I am very satisfied with this little amp.

Rated 4 out of 5 by from Its Dayton qualityBought this SA70 to ship to a friend in Greece. Parts Express does NOT ship to many European locations so I act as his middle man so he can get his Audiophile needs in Greece. Parts Express should consider shipping to these other country as there is many Audiophiles out there. If this SA70 anything like my SA100 it will be a top notch little plate amp.

Rated 4 out of 5 by from Does what it saysNo frills, basic amp for a cookie-cutter sub-woofer I bought in 2006. The original Amp finally gave up the ghost a couple months ago. Not the cleanest watts, but it only powers a 10-inch driver in a 1 cubic ft vented box. Does the job.

Rated 4 out of 5 by from like they say more suited for compact systemI'm using this sa 70 to power a pro series 200 watt rms 4 ohm 12 '' sub (radio shack) in a home built ported box . the sound is very good but the amp is lacking in power for this size speaker . It would be great for lower power speakers as stated in the description / i used the 12'' because it was there in the box for years unused on the shelf . For this speaker a 200 /300 watt amp would be great / but it sounds good so i'l stick with it !

Rated 4 out of 5 by from It's a keeper!I bought this a month ago for my old garage Sanyo 10 watt stereo with built in EQ hooked up to an old pair of Community 15 inch 2 way PA speakers. The system needed some bottom support. As another reviewer commented the sound to the woofer allowed too much of the lower mids. So, I put a 2.5 mh inductor in series with the woofer, that fixed it. As it turns out, I stuffed a towel to plug the Sub port as I am not interested in rattling things, I just want the 20 – 40 hertz to be present in my music. My sub is a 10 inch home unit I got from my son for Christmas that didn’t have an amp. The Dayton 70 watt turned out to be quite the overkill for my application. I run it at the 40 Hz setting and the power level at 2. I’m completely satisfied.Thank you Dayton and Parts Express.

Rated 4 out of 5 by from Perfect Match !!!!I bought this recently to power a 2-12 " 4 ohm subwoofer that had originally been used in a car stereo set up. My son is into vinyl. We put together a Harmon Kardon receiver with some Yamaha surround speakers speakers, and used the sub for the low end. The 75 watts output is perfect for his tiny room, and drives the speakers quite well.I am probably going to buy another one to replace the amp in my old M an K sub.

Rated 4 out of 5 by from Works well with a good speakerI use a large sealed, stuffed box with an efficient driver and the power of this amp is just fine. It was the work of a few minutes to mount the plate and wire it up. The first one I bought developed a little "groan - buzzing noise" periodically - that's why it did not get 5 stars. Overall, it is great - I can shake the floor if I want.

Rated 4 out of 5 by from Power for your music's lower two octaves: the SA70 amp.The SA70 arrived on schedule, as promised. I have put it in a box (0.6 cu. ft.) with a Tang Band 6-1/2 inch driver (PE #264-832). The Technical Department offered advice about proper tuning of this vented system. In initial listening tests, it performs better than an Advent 12-inch sub in a larger box (ca. one cu. ft.). Besides moving large volumes of air, it renders musical pitches well, so that the music has better definition from low to high notes. Imagine the lower two octaves in your recordings solid & defined without breathiness (the 'woof-woof' effect). The performance of the SA70 did not surprise me, since I have also used it to drive 8-inch drivers. It offers good value for the dollar.

Rated 4 out of 5 by from Dayton Audio SA70 70W Sub AmpNot a bad little amp for a smaller, don't have to fill the room with bass" kinda system. Used mine on a my custom built sealed enclosure 12" sub to go with my AudioEngine 2 Speakers connected to my computer. Sufficient low end 40hz was a little higher cutoff than I wanted) and basic volume control. Sealed enclosure and small package make it an easy fit, does not take up too much internal space. For the price, its an excellent choice, otherwise... if you want tons of volume, spend wisely.

Rated 5 out of 5 by from Better than stock 250w JBLI have a JBL Venue 10 sub that cooked. I got creative with a hacksaw blade in my jigsaw and cut an opening out of the stock JBL plate amp, screwed it in, and it looks factory.The SA70 amp itself was heavier than the stock 250w JBL when held side by side. Once the plate was prepped, installation was very easy (though I wish the leads to the driver were longer). The sound is amazing for a $50 sub amp! I think it may be an upgrade from the 250w JBL factory amp! Brings my basement workbench to LIFE. It was a perfect fit for this refurb/repurposing of a cooked asset. I'm glad I didn't kick down bigger $ for more wattage in this case!

Rated 5 out of 5 by from Great deal!Plug & play- My previous sub plate amp went out on my little 8" 4-ohm sub. So I bought this cheapy, and it works just as well. I didn't test the crossover, since I use the sub-out crossover in my A/V receiver. For the money, this is a really good deal. It works great on smaller subs. It's been going strong every day for a month with no problems.

Rated 3 out of 5 by from JUST BOBDisappointed with this amp.For a sub there to much higher HZ getting through.When I turned on the unit it sounded like a mono speakernot a Base speaker.The only thing I can thing of to getting rid of the mid range sound is a cross over to filter out the mid range HZ.I found a SONY SQR 6650 4 channel receiver made in 1973.Living in a 5th wheel RV there not much room for such a receiver.I installed these little 2 inch speakers along with a 6 inch sub woofer. (All sold by Parts Express)The Tang Bang model W2-18118 2 in speakers were just installed right into the walls no cabinets. 6in Sub in to a unused cavity.The 2in speaker have a HZ range from 150 to above 15000I couldn't believe my ears when I turn on the receiver. The little guys were putting out base. Ya BASE!All in All. I'm very happy with this old Quad stereo it has a awesome sound. Its 4.1 not the new 5.1 along with mycassette and LP's I have a system anyone would love.If you saw a 70 yr old doing cartwheels it would be ME. :)It a shame Parts Express discontinued carrying theseawesome little speakers.

Rated 4 out of 5 by from Perfect for the right applicationLet's be realistic about this product. This subwoofer plate amp runs 70 watts RMS at 4 ohms. At 8 ohms, it's going to run at 45 watts RMS. This is not going to shake doors off hinges or break glass. It isn't supposed to.For the average living room on a modest budget, this amp is great. If you're looking to add a little extra to your home stereo and TV watching experience, this is a good choice. I see a lot of people that cannot help but to go maximum power in anything they purchase when it just isn't necessary. These plate amps are a good example. Some people also expect extremely precise, error free, best-of-the-best type quality out of even the most inexpensive of items and they are inevitably disappointed by a product with results that are good but not amazing. This plate amp is also a good example of that.I bought this more out of curiosity than any other reason. I had been given an old Fisher sub woofer cabinet (ported) without it's own power and a rotted out cone. I also had a 12" 3.7ohm, 120w Goldwood poly woofer lying around so I married the three: Fisher cabinet, GW 12" woofer, Dayton 70w plate amp. Not "top of the line," high quality items but doing this makes these components out of storage and in use, as opposed to being dust collectors.Of course it isn't George Lucas' soundstage, it's just a simple subwoofer capable of making home entertainment better than NOT having a sub at all. I set this up in my shop, a separate building behind my house. I put it through its paces and let it run all night at about 1/2 volume after I went to bed to see if it got real hot, blew up, anything bad happened. The amp worked fine all night. It worked too well because I was woken up by the local police department banging on my back door. Sound complaint, could I turn it down. Actually, he asked "Did you have a party here last night?" And then he told me there was a complaint.I think that tells you this is not garbage with no output power. It was loud enough at 1/2 power to get someone to call the cops. And the nearest place besides my house that a person could be is about 90 feet, inside their own home. So loud enough to be audible from inside my shop, 90 feet away, inside a house. That is kind of my unofficial measure for success in the "is this loud enough?" category.I've found that I like hooking up this amp via the low level RCA connection rather than running a stereo set of speaker wires to and from it. Less mess and I like the sound better.Now. The Crossover. It is not a piece of garbage, as eluded to here. It just has way too much headroom. You shouldn't be able to have crossover frequencies as high as this one allows. You'll be pushing vocals and instrumentation not meant for subs and it will sound.... like garbage. Keep it turned LOW and I mean all the way down if not a tiny tick from all the way down.This thing would be fun with an 8" or 10" in an enclosure that is shallow, with spikes, pointed downward. I am only going to get bigger, more powerful plate amps after my initiation with this one. I always thought the concept was great, but hadn't tried one out. Now, I am in love with this product!Over all, this is a great addition to your home entertainment center if you are in a somewhat run of the mill situation with your normal sized living room, a TV you watch some movies on, hooked into your stereo that you also listen to music on. Adding this amp w/ a matched sub to that sort of situation can only make your audio experiences better.If you're looking to add a powered subwoofer to your 80" LED Internet TV on your 7.1 surround system with Left and Right floor cabinet mains powered at 200w RMS and each of the five other satellite speakers at 140w RMS in your 40 foot by 60 foot home theater- this is not the product for you. This is probably something a person like you would want installed for his second bathroom audio system.

Rated 3 out of 5 by from Seems cheap...I had this powering an 8" Dayton sub for about 2 months and it started sending a hissing noise with an odd chirping sound every couple minutes. It sounded alright for a while. Terminals are also annoyingly small. Output seemed kinda sporadic. Filters are pretty much useless. I sent it back for store credit so I'm gonna try out the 100 watt model. Hopefully have better luck.

Dayton Audio SA70 70W Subwoofer Plate Amplifier

I am building my own subwoofer and wanted to make it Bluetooth. How do I connect your Sure Electronics Bluetooth 4.0 Audio Receiver Board since the sub plate is sealed on the inside

Asked by: jeffkopp
The connections would have to be made outside the enclosure by wiring the RCA outputs of the Bluetooth board to the RCA inputs on the amplifier. Power for the board will also have to be an external 12VDC power supply.

So i'm looking at powering two of the AuraSound AST-2B-4 Pro Bass Shaker Tactile Transducers with one of these amps at 4 ohms. Will this work? I saw a q&a on the shakers page that said otherwise. Thanks,

Asked by: joocyj
The problem with using this amp is that the two shakers will have to be wired in series, which means each shaker will only receive about 20 watts. An SPA250 or APA150 would be a better choice for a pair of shakers.

Asked by: jeffkopp
Not necessarily. As long as the woofer is 4 ohm and in an appropriate enclosure, the wattage rating does not have to match. Anything from 50-100 watts RMS will work with this amp.

Is it bad that it heats up?

Asked by: luis975
This depends on how hot it gets. This amplifier will get warm while it is being used and may be slightly warmer than room temperature when in standby mode. If it is being used relatively hard, it may get somewhat hot to the touch but this is normal.

The specs say "45 watts RMS into 8 ohms • 70 watts RMS into 4 ohms". How do you tell this amp which ohms you want to use, or does it switch automatically between 8 and 4 based on the speaker you have hooked up?

Asked by: Jammer134
The speaker that is hooked up provides the load to the amplifier. If you want the full 70 watts you will have to use a 4 ohm speaker, if you have an 8 ohm it will only produce about 45 watts.

I have a Pioneer VSX-823 receiver which has a Preout Subwoofer port. I want to connect it to my old passive Polkaudio RM1000W subwoofer which only has hardwired LR channel connections. How can I connect the Preout Subwoofer cable to this amp?

Asked by: Will49
The preout on the receiver will be plugged into the right line level input on this amp. The subwoofer will connect to the red and black wire on the back of the amp. If each input on the subwoofer is 8 ohms, they can be wired together in parallel for a 4 ohm load.

I have a passive subwoofer (8 ohm, 10-100 watts) and two speakers (6 ohm, 50 watts) powered by a 2 channel 90 watt amplifier. From my audio understanding, this is missing major power. How would I connect all those to a plate amplifier or another option?

Asked by: beatles1
You will have to use the speaker level inputs and outputs on the subwoofer amp in order to get it wired properly. The speaker outputs on the stereo amp you have now will be wired to the "From Amplifier" terminals on the subwoofer amp, and the satellite speakers will be wired to the "To Speakers" terminals. The subwoofer will be connected to the red and black wires on the back of the subwoofer amp.

Im curious why this amp has left and right channel rca low level inputs when there is only one set of leads to the subwoofer. How can it separate right and left channel information to a dvc sub or two subs with one set of input leads

Asked by: banzai63
This amplifier combines left and right signals for the output to the subwoofer. If you are using a DVC woofer, you will have to wire the coils together in series or parallel as long as the load does not drop below 4 ohms.

I am sorry, we do not currently have a box that will cover our subwoofer amps. It is a good suggestion though so I will pass it along to our new products guys.

I bought two of these amps to power stereo PUCK  bass transducers for my racing simulator project. Two questions actually. Do the line level and speaker inputs function at the same time? Also, does the speaker level pass-through affect impedance? Thanks!

What do you recommend for 240V installations in about the performance range of the SA70?

Asked by: Bodgie
The closest option would be the Yung SD100 which has a switchable input voltage.

i just recently purchased this amp to power 1 aura bass shaker. i have the gain half way. it runs amazing. but after 30 mins of use, the plate was hot. is this normal? and how long can i run this amp if i play a continuous 75Hz test tone

Asked by: hannibal
These amplifiers will get quite warm or hot if they are fed continuous sign waves.

I have this exact amp. It suddenly stopped working. Is it possible to purchase replacement parts (circuit boards, capacitors, etc.)??

Asked by: Kamau5
Unfortunately we do not offer replacement parts for these and they are not practical to repair. If the unit is within the 1 year warranty please contact tech support so we can see about getting it exchanged.

I have a 12" sub from a car.  Can I hook this up to the sub, plug it into my Sony receiver with a A/V cable and have a powered sub to fill out my home theater? I got the sub for free and want a powered sub for the HT system.  

Asked by: Tridaddy
Yes this is the type of amplifier you would want to use for that. You will need to make sure the subwoofer is 4 ohms or above so the load on the amp will be safe.

how can i wire 3 tang band W5-1138SMF's to this

Asked by: Bassbalaster505
The only way you can safely wire three 4 ohm subwoofers to this amp would be to wire them all in series, which will only provide about 23 watts of total output power from the amplifier. You would be better off using 4 subwoofers wired in series/parallel and a slightly larger amplifier.

Can this amplifier be modified to boost the eq curve?  Is there a published table with resistor values for given frequency and boost levels?  Thanks.

Asked by: firefox319
Unfortunately this amplifier cannot be modified in any way.
