I recently dynamatted my whole cab, and when I went to plug everything back in, my sub has basically no power. It has a tiny amount of power, but it's next to nothing. I checked the voltage at the amp +/- terminals and remote wire, they're getting plenty of juice. But something's happening when the power leaves the amp.
I'm not sure what I need to be looking at... what should I be looking for while checking the terminals at the speakers? What about the RCA inputs? Should I check the fuse behind the head unit?
Sub is an SWR-12D4
Amp is MRX-M50
HU is Pioneer DEH-P600UB
