Well the amp I have is actually nothing great, just an old Rockford Fosgate that is rated like 300 watts (RMS) x 1 or something like that so yeah nothing powerful at all. The subwoofer completely just died, doesn't make any noise & I wasn't even playing it very loud either. Now I wouldn't now if my amp is getting a stable voltage or not but I do know that the amp still power on & puts on power. I mean I've been running 2 amps and with this setup for years and just all of sudden experiencing problems; more so with the amp for the sub. Any more suggestions? Thanks!

but I will say that the amp your running will only realisticly do around 1500 rms at best. and considering you said you were running a cap. and not a second battery, and that your 4 ch is run also off that power line, your probably dropping close to 12 volts if not lower. Be careful with that amp because they have a tendancy to not like anything below 12.4 volts. and with enough time played below that voltage you will end up blowing the amp.
