Rated 5 out of 5 by from Great easy to installI got the speaker at a flea market and it never worked good. I was going to throw it away then went looking on the net for a replacement amp when I found this one Couldnot be any easier to install plug in the speaker wires screw the amp in place and you are good. Did have to trim the opening a bit but sounds great.

Dayton Audio SA70 70W Subwoofer Plate Amplifier

Hello, is possible connect to 220v europe domestic voltage?

Asked by: andresdd

I have a Polk PSW10 with a blown amp; out of warranty, of course. Will this plate amp work with little (or no) modifications? Polk wants almost 2x this for a replacement part.

Asked by: OldGoat
We do not have a direct cross reference available unfortunately. The dimensions are listed on our site for this amplifier, so you should be able to compare those to what you have in terms of overall size.

What are the dimension? Also' is a out-of-the-box 6" 4 ohm passive subwoofer compatible?

Asked by: Shelbyfastback65
Yes this will work with just about any 4 ohm woofer and should be no problem with a 6".Dimensions: 7-1/2" W x 8-11/16" H x 3-1/2" D • Enclosure cutout: 6-5/8" W x 7-3/4" H.

From the pictures I can see that the back of the amplifier is sealed in. I am trying to design an enclosure for a Dayton Audio DCS205-4 using this amp. What is the volume displaced by the amplifier so that I can factor it into the enclosure design?

Asked by: Drewrf
The volume the enclosure on this amplifier displaces is 0.10 cu ft.

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.
