Dayton Audio SA70 70W Subwoofer Plate Amplifier
Im curious why this amp has left and right channel rca low level inputs when there is only one set of leads to the subwoofer. How can it separate right and left channel information to a dvc sub or two subs with one set of input leads
This amplifier combines left and right signals for the output to the subwoofer. If you are using a DVC woofer, you will have to wire the coils together in series or parallel as long as the load does not drop below 4 ohms.

Is ther a parts express project box that will fit this amp?
I am sorry, we do not currently have a box that will cover our subwoofer amps. It is a good suggestion though so I will pass it along to our new products guys.

I bought two of these amps to power stereo PUCK bass transducers for my racing simulator project. Two questions actually. Do the line level and speaker inputs function at the same time? Also, does the speaker level pass-through affect impedance? Thanks!
I'm not sure why it made me anonymous, but it wasn't intentional. My name is Tony. Any help is appreciated!

What do you recommend for 240V installations in about the performance range of the SA70?
The closest option would be the Yung SD100 which has a switchable input voltage.http://www.parts-express.com/yung-sd100-100w-class-d-subwoofer-plate-amplifier-module-no-boost--301-500

i just recently purchased this amp to power 1 aura bass shaker. i have the gain half way. it runs amazing. but after 30 mins of use, the plate was hot. is this normal? and how long can i run this amp if i play a continuous 75Hz test tone
These amplifiers will get quite warm or hot if they are fed continuous sign waves.

I have this exact amp. It suddenly stopped working. Is it possible to purchase replacement parts (circuit boards, capacitors, etc.)??
Unfortunately we do not offer replacement parts for these and they are not practical to repair. If the unit is within the 1 year warranty please contact tech support so we can see about getting it exchanged.
