Disconnecting/Reconnecting Sub
Alright so I had to disconnect the sub box in the back of my jeep so I could transport a grill. I went to hook it back up and now it won't work at all and I have no idea why. The amp that powers the subs is on and working, my receiver shows the settings for the subs as being on and not deactivated. The system was installed back in 2006 and the shop that did it is no longer around. Any ideas on what to do next?

Re: Disconnecting/Reconnecting Sub
did u leave the wires hooked up on the amp?
like have the wires open and lose. bc if the ends touched they could have shorted out the speaker terminals on the amp

Re: Disconnecting/Reconnecting Sub
Yeah all I did was unhook the wires from the sub and left everything else alone. I've done it before and never had any problems except for this time.

Re: Disconnecting/Reconnecting Sub
yeah, if they had open live wires that could easily be the problem

Re: Disconnecting/Reconnecting Sub
Thanks for the heads up. So I could be looking at a new amp?

Re: Disconnecting/Reconnecting Sub
yea most likely. maybe take it apart and see if they have a fuse that can be replaced. or if you have the cash. buy a new one

i cant see the pics , but first off try another speaker on it (doesnt have to be a sub, just to see if there is a signal). and if that doesnt play then try another amp (if you have one) and check to see if the rca's came loose. but it sounds like the speaker lead shorted out. i hope its something easy.

Re: Disconnecting/Reconnecting Sub
Thanks for all your help guys. I'll have to see what I come up with.

Re: Disconnecting/Reconnecting Sub
did you just leave the wires sitting there after you removed the sub then powered up the system?

I am guessing you shorted out your amp.

Re: Disconnecting/Reconnecting Sub
Where is the amp mounted, on the box Im assuming? You left the power, ground and signal wires just laying is so I'm also assuming? For future reference if you are just leaving exposed powered wires laying around even for a short time and you need to use the car, you should heat-shrink them or cover the ends just so something like that cant happen :)

Definitely before you guy out and buy an amp check everything over. If the amp is 100% on, check to see if the signal cables came loose or possibly something behind the deck came loose, you never know. Also check all your fuses, this is just a standard check, you said its getting power though so shouldn't be an issue.

Really the amp being on just means it got the turn on signal and is grounded, doesn't necessarily mean its getting enough power to push the sub. Check with a MM the voltages and that will give you some more info.

Also just to rule out the sub being a gonner, you can pop a normal 9V battery onto the sub terminals and see if it moves, if its ok it should move. If the sub moves which it should its safe to say its your amp and something went haywire somewhere. most audio shops will take it apart and look at it too see what's wrong for very cheap. Fixing it is another story :( hope that helps some.

Re: Disconnecting/Reconnecting Sub
Both amps are actually mounted on the back of the rear seat, but yeah, lesson learned.
