Thank you for all the information.
So is the suggestion to go back to a non-bridged setup? Also it install a system volt meter to monitgor the voltage levels so I can make sure I am adequately charging the system?
I would leave the amp like it is, but adding a voltage indicator would take the guesswork out.
Leaving 2 speakers in parallel across 2 channels will potentially damage your amplifier, especially if the voltage is dropping below 12v. The Amp is 4 ohm stable bridged, not 2 ohm. See my first post. Rewire to a stable load and if you can use an oscilloscope to tune the gain for a clean signal.
The only easy day was yesterday.
