my soundstorm amp wont turn on?

If you have access to a multimeter, I'd check all the lines going into/out of the amp.

With everything turned on, connect the ground of the multimeter to the car chassis (bare metal) and check for voltage on the positive (hot) lines, you should get a reading somewhere between 11-14 volts. If you don't get a reading, the line is not sending power. I'm assuming your main is getting power if the capacitor powers on, but what about the feed from the stereo?

If all the positives are fine, hook the positive end of the multimeter to the main power for the amp, and hook the negative end to the amp ground.

If you don't get a reading, the ground is bad/corroded. If you do get a reading, that means the amp is screwed up and will probably need servicing.

You could do this with a 12 volt test light too, but a multimeter is only $20-$25 for a descent one at Home Depot, Menard's, WalMart, etc.

Good luck!

easiest way to find out if amp is good.. disconnect and try in friends car.. do it all the time.. lots of times ppl think amp subs ect is gone.. but i hook it up to my car and its good.. so try it on someone elses car.. if it works.. check loose connections ground remote.. wiggle power wire by fuse.. sometimes it gets messed up.. this guy had best buy install his stuff and they did the wire so tight there was no room to play or work. i guess it stretched until it was loose n not u have to bend the power wire for amp/sub to power on.. hope this helps.

1. The capacitor could be shot. or 2. The amp may have been fried, you said that it overheats, well the protection device may have malfunctioned.
