Two days ago, my system was playing fine, next thing I know, it stopped working. The place I got it done at left my stock sub inside, which is still hooked up by the way. ( I didn't know until my subs went out).

Anyways, I have 2 JL 10w1s in an enclosed box, with a 720 watt pioneer amp pushing them.
Any idea what the problem could be? Maybe the fuses went out on the amp? I don't really know much about car audio.
thanks everyone

 

check the fuses; check the ground

 

Absolutely the first steps. Eliminate the easy things first.

You might also check your RCA cables, and any other single point of failure in the system. It's likely not your speakers, but could be your speaker wire if they somehow all got pinched in a weird situation. You should also check over the remote wire connection.

If it's none of those things, then it could be a bad head unit (or bad output on the head unit), or a bad amp. Everything fails at some point, and it's always hard to believe. If an extra sub was attached to your amp, then they changed the impedance of the load on the amp. It is probable that you shortened the life of your amp by driving an out of spec load if those things are true.

 

few other things....does your amp kick on at all? if not check the ground wire. i recently had mine go out in my car and had to run a new/larger one since the other one went bad after 3 years

 

1.fuses. by battery
2.ground.
3.remote line
4.fuse on amp
5.rca
6.ground..

i have had that too hit a speed bump my ground came loose... i was stubborn and kept saying its not my ground. i ripped apart my whole system to find out it was my ground it was holding but i pulled it out of the ring without any force... and fix....

 

i took it to a place, and i blew a fuse apparently. well they fixed it.
