Product Details

Dayton Audio SA100 100W Subwoofer Plate Amplifier

Small but mighty! The Dayton Audio SA100 high performance subwoofer plate amp module packs big-amp features into a compact chassis that is ideal for installation into cabinets that can't accommodate bulky old-style amps. We made it small, but included everything that you need to connect the amp to your system and get maximum performance. Input/output connections are through your choice of either line level RCA connectors, or speaker level banana jacks. A stereo input signal is summed to mono and sent to the internal low pass crossover, which is selectable from 40 to 180 Hz; the input gain sensitivity is fully adjustable as well.

The SA100 also includes a phase reverse switch, which helps you to achieve the best acoustical match with the rest of your speakers. An Auto On/Off switch keeps the amp standing by, waiting for an input signal to turn it on. A large surface area heat sink is combined with internal overload, thermal, and short circuit protection so that you can expect years of reliable operation.

Specifications: • Measured power output: 75 watts RMS into 8 ohms @ 0.1% THD, 100 watts RMS into 4 ohms @ 0.2% THD • Signal to noise ratio: 90 dB (A-weighted) • Dimensions: 7-1/2" W x 8-11/16" H x 4-3/4" D • Enclosure cutout: 6-1/2" W x 7-1/2" H • Power requirements: 120 VAC, 60 Hz, 180 watts • Net weight: 7.6 lbs.

Dayton Audio SA100 100W Subwoofer Plate Amplifier
Dayton Audio SA100 100W Subwoofer Plate Amplifier is rated 4.5294 out of 5 by 119.
Rated 5 out of 5 by from Great quality and reliable!!I bought 2 of these SA100 plate amps back in 2003 and they have been great. They have out lived two of my other store bought powered subs. They do not hiss or hum annoyingly like some old or cheap subs and the AUTO on/off still works like the day I got them. Under normal use they run warm and under heavy use they do get a little hot but has never been a problem. Over all I would buy these again any day and have recommended them to many friends.

Rated 5 out of 5 by from great valueMy previous sub amp had a constant hum and no auto on/off. I replaced it with the SA100 and it works perfectly. Great sound, no hum and auto on/off. I am very satisfied

Rated 5 out of 5 by from Great amp!I bought this to replace my old Dayton 25w plate amp that I have had for over 10years and which now has been moved from den sub to bedroom re purposed passive Bose passive sub.. I am running the Dayton 100 at 4 ohms connected to my Polk C4 car sub which I use as my primary music sub (Sony ES receiver, den / stereo music room). The sounds is fantastic, very responsive, low low distortion, good build, stays cool under load and pounds overall. I would buy it again and again. Thanks Parts express!

Rated 5 out of 5 by from 100 watt of goodnessBuilt an 8" sub for my desktop pc and required a amp to give it some powerMy sub is rated for 300 rms and total of 500 watt peak. I wasnt sure this 100 watt plate amp would be enough to power the sub. After reading the reviews i went ahead and made the purchase. To my surprise this amp is more then enough to power a loud sounding bass thumping sub. Im very happy with the purchase. My sub is wired to 4 ohms to recieve the full 100 watts. The crossover built in does its job to filter highs. You wont be dissapointed. Keep in mind the size of your sub.

Dayton Audio SA100 100W Subwoofer Plate Amplifier

hi I have a cerwin vega ve28s subwoofer with dual 8" subs. The plate amplifier is bad and is rated for 125rms/250 peak. the Dayton audio sa100 is rated at 100watts rms. what is the peak watts? do you think this amp will work for me?

Asked by: james352
As long as both woofers combined have an impedance of 4 ohms or higher this amp will work. Unfortunately there is no peak power rating for this amplifier.

I am really new to all of this, and now I know what a plate amp is.  With that said, I am using it to drive a pair of bass shakers and I am wondering if there is an enclosure I can buy to make the unit a stand-alone near the shakers?

Asked by: RickP
We do not have an enclosure specific for the amplifier although we have a few small knock down subwoofer enclosures that will work. Something like below will be a good option.http://www.parts-express.com/knock-down-mdf-067-cu-ft-subwoofer-speaker-cabinet--300-7068

i have a sa100 amp powering 2 pioneer (ts-w80c)8 inch woofers (400w,4ohm) . when I crank the juice from the receiver very high, the amp cuts out , why. what do I need to do.

Asked by: GABB
This depends on how the subs are wired. If they are in parallel the amp is likely shutting off in thermal protection mode due to the 2 ohm load. They will need to be wired in series for a safe load on the amplifier.

I am interested in buildging a sub with this amp and the epic 10 driver. Is there a 230VAC  version of this amp for use in europe? Thanks in advance

Asked by: Nicolas2000
Unfortunately we do not have this amplifier in 220V. I would recommend a bit more power for that woofer anyway. You might want to consider the SPA250 which does have a switchable input.

I'm looking to retrofit this into an existing enclosure. The only depth dimension given is 4-3/4" for the unit, but I need to know the depth this needs inside the box measured from the plate flange (to avoid interference with the driver itself). Thx.

Asked by: russella
The actual mounting depth of this amplifier is 3-1/4" from the back of the flange.

Which outputs should I attach my Bass Shakers to?

Asked by: albrnick
The bass shakers are wired to the red and black wire leads coming from the back side of the amplifier. Depending on how many shakers you use, they may have to be wired in series/parallel to maintain a safe load to the amp.
