So installed an alpine 5-channel amp the other day. Its a 4-channel amp plus sub driver. I built my own custom pc enclosure and forgot to ground the powersupply to the chassis so i ended up getting a big ground loop. I think i blew the sub channel on my amp. Does anybody know if this is possible. or how i can check to see if this is what happened. The rest of the amp works, just not the sub channel anymore. thanks for your help.
it is possible to blow that channel on it's own.
Several 5 channel amps out there use a class a or class AB (usually AB) for the 4-channel and a seperate class d for the sub channel.
Do you happen to know which series/model etc amp?
other than making sure your sub isn't blown (take another sub and plug it into that channel) and / or ditching the wire that's connecting the channel and sub currently to make sure it's not a wire issue....not sure how else you would test it on your own.

Please post on the forums! Chances are, someone else has or will have the same questions as you!
Need more details on the setup and what works/what dosn't work and what you want done for a proper diagnostics.
