2 different amps, 2 different subs, not working...

[Imperial GOD 10+ year member]

So I have a JL Prowedge box with 2 12w3v2's and a JL 12w7 in HO Box

I also have a Kicker Old School 500 watt amp, and a JL 500/1 amp.

Here's the story....

I had the 12w3v2's with a Kicker amp, then upgraded to the JL and the 12w7.

Everything worked fine.

My amp kept cutting out, and I couldn't figure out why. I finally tore the **** trunk apart and found out the end of the ground wire was disconnected from the piece that I had screwed to the car. I pulled the ground out and disconnected everything. It's now a couple weeks later, and I decided to rehook it up.

I took the piece off the car, opened up the clamp with some needlenose pliers and then clamped them back down on the ground. Looks good so far... I then put the amp in the car and connect the positive, I then connected the Positive connection and the remote. I turned on the car and the amp powered on. I hooked up the subs and there is no sound. I then took a RCA to headphone jack and tried my ipod to the amp to see if I could get sound from there. Nothing. so I pulled the remote wire and the amp stayed on..... now that confused me.

I then changed the subs, and there still was no sound.

I then changed from the JL 500/1 amp to the Kicker amp, same thing with both subs.

Now I'm really confused, does anyone know what it could be? Should I change out the Ground wire or do you think both amps are shot?

Any help would be GREATLY appreciated.

It's not sounding good for your amps. However, I'm concerned with your wiring habits. Twice you mention either wiring or unwiring something to the amps while the system is hot and powered on. I hate to think about all the times you may have done that in the past, that you haven't mentioned.

Anyway, get a voltmeter. Check the input voltage to the amp and remote wire, make sure they're both 12V or better. Then, feed an audio signal to the amp (your ipod with adapter will work fine for this, turn up the ipod volume all the way), then check the speaker outputs with the voltmeter. You should get a voltage reading that's jumping all around like crazy, if it's good. Make sure the gain on the amp isn't set on zero. If you get nothing, then yep, the amp is in need of repair.

Hope this helps!

Thanks Kevin, I'll check into it. I'm going to be pissed if both my amps are shot to shit....
