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, 210 watts • Net weight: 7.6 lbs.

Rated 5 out of 5 by from Small, yet powerful.Purchased this to replace a large AVR amp that I was using to power my Aura Bass Shakers. Hookup was simple, great build and finish. I made a small 1x4 wooden box to fit it in. Takes one quarter of the space of the old amp. Very happy with my Parts Express purchases.

Rated 5 out of 5 by from Fits like a gloveReplaced a blown by lightning KLH Audio Systems S70EIH plate amp. Had to switch 1 woofer spade from small to large. Fit perfectly into existing woofer cabinet and has same electronic crossover features. Binding posts and heat sink are a plus over original unit. Sound quality is better than original unit. Excellent product.

Rated 5 out of 5 by from Just what I neededI bought this to replace the original manufacturer's amplifier in an old sub-woofer. This one from Parts Express installed where the old one came out, almost perfectly. Very happy with the easy installation and the performance. I'm using this to drive a 12-inch woofer.

Dayton Audio SA100 100W Subwoofer Plate Amplifier

Hi, can this part be used in place of Velodyne CT-120 amp plate to drive 12" sub? Thanks.

Asked by: Kavi
As long as the woofer is 4 ohm this will work, although it will probably require cabinet modifications in order to fit properly.

Will this amp fit in the cabinet of a Dayton SUB-120 without much cabinet modification?

Asked by: KayCee
We have not tried this, so we cannot officially say whether it will work. Of course, this type of modification to an existing product to accommodate a different amp than it was designed for will void your warranty. Some amount of modification would be necessary - any type of air leakage from the enclosure (except air movement thru the port) will generate extraneous noise and diminish the enclosure's effectiveness.

Would the Main output from a mixer connect to the Low level or High level inputs? . I currently have the connection to RCA using the pass thru to an Aphex audio exciter to Amp to main speakers but don't get very much response till SPA250 is at 70%

I purchased this amp to power a Clarksynthesis model TST209 transducer. The issue is the amp shuts off when the music gets louder or in a movie when a lot of low end is being used. Do I need a stronger amp or is there something I can do to this one?

Asked by: Radiojunkee
As long as you are only powering one transducer this should be a good match. If you are running it at high levels consistently you may consider bumping up the power to something like our SPA-250, that way the amp is running at about 50% during high levels.

Hi ...Can I use a plate amp to a single subwoofer for each channel? I want separate right and left sub woofers. I want to use the "amp" inputs to the plate amp.  Thanks, Zene 

Asked by: Zene
Yes, you can use a subwoofer plate amplifier this way. Just connect the respective input wire to each subwoofer amplifier as if you were connecting a single channel source (like your receiver's LFE output). Then you can use the plate amplifier's volume and crossover controls to tailor the subwoofer output to match the rest of the main drivers for the most balanced sound.

Will this unit deliver sufficient power to the Musica M800SW 8" In-Wall Subwoofer (100W RMS @ 8 ohms)?  And can this amp be wired in bridge mode to deliver more power to this one subwoofer?  If so, which speaker terminals should I use (L+ and R-, etc.)?

Asked by: Matchless
This is a mono amplifier and only has one output for the woofer. Even though you will get less output power at 8 ohms, this amplifier will still work well for that subwoofer.
