got a Ultimate T3-500D used it for about 1 maybe 2 months then my car was acting up so i took the plates off and it sat for part of the winter.... so now that it has warmed up i go to start it..battery dead...fix that start it n it runs good so i go turn on my stereo and no bass nothing has been touched it just say for like a month or two.

The LCD displays and logo on top light up but the power protection LED that usually is blue does not come on.

All fuses good, power wire, remote wire, and RCA's all checked and not the problem.

Tried to take the bolt off of the ground cable just incase some rust is bother it, but i couldnt get the bolt loose with a wrench cuz its soo damn tight haha (started to slip and strip the bolt )

What should i be looking at, tomorrow i plan on trying to get that ground wire off and checking that but im sure it cant be that

.:edit:.
just ran outside took booster cables and hooked one end to the bolt that secures my ground wire and hooked other end on battery NEG ...still nothing, that should have worked if i had a bad ground eh?

 

I had a Sony Mobile ES 4 channel amp that did that to me on 2 channels. What had happened is that during winter, the amp would heat up, cool down, heat up, cool down, and condensation would build up inside, finally frying the outputs on 2 of the channels, sadly the ones running my subs. Had to send it away to get the output stage replaced. Hope you dont have to do that.

 

hope thats not my problem too... exept the power/protection light was always on (blue) and now its not on at all

How expensive of a fix is that?

 

i would bring it to your local car stereo shop and get them to test it , or just beat it with a hammer

 

my local car stereo shop is like 2 hours away haha

 

It cost about $150. Luckily, the shop I bought it from sent it away on warantee for me.
