I'm having some problems with my amp, and I'm trying to find the source of the problem.

The voltage on the RCAs is how the signal is transmitted. It has nothing to do with the power supply of the amp, but there is voltage there.

Okay...so I should get a reading on my Volt ohm meter...correct?

Yeah. Assuming that your deck has 4V outputs, you should get somewhere in the neighborhood of 4V with the volume at max.

Werd...I do believe I have a blown pre-out then. I appreciate it bro.

you're probably not going to get much of a reading on a DMM unless you're playing a test tone.

Depending on what range you have it set to.

record a 0dBFS sine wave at like 1khz (find nch tone generator), put that on a cd, play that with all dsps off (including any high/low pass filters) at full volume, then measure.
