Dayton Audio SA230 230W Subwoofer Amplifier
Dayton Audio SA230 230W Subwoofer Amplifier is rated 4.4545 out of 5 by 33.
Rated 3 out of 5 by from Great amp, except...I am using this amp to drive the woofers of a pair of Polk RTiA7s. A Denon receiver is doing the x-over duties and driving the upper end. It is amazing how much better the system sounds with bi-amping compared to just using the receiver.Very nice amplifier, except for the auto-on feature. It needs a fairly high level input to turn on. Listening at normal levels will not trigger the auto-on or keep the amp on. You have to really be rockin' it out to turn the amp on and keep it on. At least with my set up. So, for now, I am manually tuning the amp on and off. Not a big deal. But in this day and age, an amp ought to know when it has a input signal or not.I design circuits for a living. So when I get a chance, I will open up the amp and find the input to the comparator that triggers the auto-on function. It should be an easy resistor change to increase the sensitivity of the auto-on function.If the auto-on worked better, I would give this amp a 4 start rating. 5 stars if it wasn't made in China.

Rated 5 out of 5 by from Good amp for Bass ShakersI bought this amp to run 4 bass shakers in series-parallel. I have been impressed with the amp and its adjustments to allow me to fine tune the shaking with my subwoofer to get the right amount of sound and shake. I have 2 reclining two-seaters and mounted a pair on each and there is incredible shake and room for much more if I turned up the LFE channel and increased the gain on the amp. I looked at Dayton Audio SPA250 250 Watt Subwoofer Plate Amplifier as well. For my use, the $75 was worth it to not have to build a cabinet or mount it in the wall and buy various other parts to make a clean installation. I was also fine with the trade off of 233W with this amp versus 252W with the plate amp at 4 ohms. Because all the amp is doing is shaking my chairs I don't think the THD of 1% is relevant versus 0.1% for the plate amp. One minor downside, as mentioned by another reviewer is that the auto-on requires much higher line level to trigger than my sub, though at theater listening volume it does come on, however with music listening volume it is less likely to turn on. Also, as mentioned by another reviewer, the 12v trigger requires attachment of wires rather than a plug. Overall I would highly recommend this amp for this particular application.

Rated 5 out of 5 by from Just a very nice productThe amplifier is housed in a nice basic metal cabinet, large bolt on the bottom which holds it's large transformer. The amplifier is completely quiet, I was worried about 60 cycle hum, no hum from this amplifier. Lots of good adjustments, it was a real upgrade to my Definitive Technology PF 1500 power plate, no comparison. I can see no downsides to this product, would purchase again in a heartbeat.

Rated 5 out of 5 by from very good subwoofer Amplifier.I bough this Amplifier two weeks ago I must say I love the sound you talking about shaking the walls very good power.

Rated 5 out of 5 by from Great features & sound qualityI purchased this Subwoofer Amplifier a few weeks ago and I'm totally satisfied with its performance. I connected this amplifier to my surround sound receiver by running a cable between the subwoofer output on my receiver to the LFE input on the Dayton Subwoofer Amplifier. I then connected (in parallel) two 15 inch 8 ohm air suspension speakers to this amp and turned it on. I then made a couple adjustment to fine tune this amp to my speakers and then listened with amazement. I have never heard my speakers sound this good. The bass response was well defined and undistorted even at high volume levels. And it sounds just as good at low levels of volume as well. It's a Great Amp !!!

since my amp went out in my cerwin vega clsc-12s can i use this amp and if so what wiring procedure do you recomend from speaker in the sub to this amp . just a rca plug or ya tell me

Asked by: jackman3
Yes you can use this amplifier for that application. The RCA from the reciever will get plugged into the LFE input on the back of the amp, and the subwoofer output will be wired to the woofer in the subwoofer.

Will the speaker terminals accept banana plugs? Spade lugs? Bare wire?

Asked by: Todd H
These are standard binding posts so they will accept bare wire, bananas, speaker pins or spades.

Are rack ears available or ship with the SA230 model?

Asked by: 1trusted1
Unfortunately this amplifier does not include rack ears or have any available separately. It will have to be placed on a shelf if used in a rack system.

I've plugged in a sub cable between my Yamaha receiver's sub out into the LFE on this amp, then wired the sub out ports from the amp to the sub.  I'm just getting a cyclical hum out of the amp itself and no sound from the sub.  Any ideas?

Asked by: DaveWantsBass
If the amplifier itself is humming there is a problem. Please contact our tech support for more help with this question, or 800-338-0531 x1.

I just bought the Dayton SA230/2VS8 Dual Subwoofer System Amplifier Package and would like to know how to wire the two subs to the amplifier since the amplifier has only one sub-out.   Please advise.

Asked by: JJMcD
On the second page of the manual below, you will want to wire each subwoofer using the 8 ohm single channel illustration, then wire both subwoofers to the amplifier in parallel.
