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 4.525 out of 5 by 120.
Rated 4 out of 5 by from Great Little AmpI purchased this for a small dorm room subwoofer project. I paired this with an 8" Dayton Audio driver in a ported enclosure. There is no audible noise, either through the sub or the main speakers that connect to the subwoofer outputs. The reason for 4 stars is that the line level outputs do not have a high pass filter. The frequency knob on the amp only adjusts the low pass filter going directly to the sub driver. But overall, a great product.

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!

Dayton Audio SA100 100W Subwoofer Plate Amplifier

Do the RCA pass-through's have a crossover on the output side? If so what is the crossover point/slope.

Asked by: RangeBishop
The RCA outputs are a simple pass through, there is no high pass in line.

I'm considering this amp for a project that I have. The sub that I have is 4 ohms and rated at 150watts RMS. Will this amp power it or should I upgrade my wattage?

Asked by: keith9422
This will power a 4 ohm 150 watt load with no problem.

I have a Polk Audio Atrium Sub 10 with dual 8ohm voice coils. Will this amp power that sub??

Asked by: Theseventhson
Yes this will work with that subwoofer, simply wire the coils in parallel for a 4 ohm load.

Will this amp be enough to run 4 Aura AST-2B-4?

Asked by: ajamils
This can drive 4 Auras wired in series parallel, but I would recommend a little more power for that personally. I typically recommend at least 200 watts to drive 4 of them.
