for the ones using the Dayton 408
are you using the rca inputs from the head unit

or the high level inputs for signal into the DSP

Dost it matter either way?

I think most people use the RCA inputs unless hooking it to a factory deck ..

Yes 3.2 volts I think is the input max

i will be measuring the head unit voltage to get a max volume available
