Need HELP with my system!!

Ok, i have problems with my subs and amp, and there are so many possible causes, i have no idea where to start. so i will start with the problem:

My amp will turn off after a while, its a different amount of time each instance. Alot of times, when i turn up my volume loud, or fade the stereo towards the back, it will shut off then. Today, i adjusted the ground wire, and the line output converter and now the amp will turn off after a few seconds.

At first i thought it was the ground wire. I have a ring terminal attached to a bolt on the body, and i made sure to sand all the paint off. It isnt tightened all the way, but it still makes contact, could that cause a problem?? Also, where the ground wire goes into the amp, there is a lot of access wire sticking out, but there is still enough to make contact with the connection in the amp, but i didnt know if that could be the problem.

also, i think it could be line output converter. Its pretty ghetto, like the back of it is totall broken off, i taped it back on, haha. is there any way to test if this is the problem, besides buying a new one.

i figured the amp is shutting off to protect itself, ive heard amps sometimes shut themselves off when there are problems, so i assume this is what is going on, but i suppose my amp could be bad.


finally, whenever my amp is on, my subs do not hit hard at all. I had the same setup in my integra, and it hit 20 times harder. I figured since i am using a line out converter, and its tapped into my rear speakers, that could be the reason why it is so weak. That, and the fact that i think on my subs is blown, but its hard to tell because they hit so weak.

Please help me out here. thanks

Need exact setup setup and specs on the Amp and subs. Need to know exactly how you have them wired.

So nothing is bridged? You simply have one channel going to one sub and the other going to the other sub?

What subs are these and what model amp?

Sounds like the amp is going into protection mode when you crank it up which means its wired up wrong or pulling lower ohms than its suppose to...
