everything is basically new, but not working

[punchme]

I have 2 amps and I was trying to run my subs from my 2 channel amp and everything else off my 4 channel amp...My 2-channel won't run my subs, it keeps cutting out in protection mode. I know to start with ground wires, but what is considered a good ground? amps are either going to come on or not, so with a bad ground they won't come on at all. I rewired everything, and then rewired again, this time using 4- gauge alll the way to the distributer block and then had to downgrade to 8 gauge to my amps. I rewired my woofers. I'm using good speaker wire that came off a roll, I cleaned the battery good..2-channel is cutting out on protection overload as soon as I put power to it. My subs are 10 inch 4ohm P1 subs, which I think are trash. I already burned up 2 JL's and 2 Sony's which I think are bigger junk. I've owned Fosgate stuff all my life. The new stuff seems to be junk. Thank you kindly for any help in advance.

single 4 ohm subs?

Unsure but I think it's a dual voice coil.

if they're single 4 ohm subs, im guessing they are each wired into a channel at 4 ohms. In this case, chances are you not getting very much power to each sub, so your gain is probably set too high, throwing the amp into protect.

what amp is it?

or he is low impedence...you breaking subs sounds like gain issues to me...get the wiring correct and then set the gain with a dmm

I have P404, P5002 Supergumby5000. I thought all the P1 series are dual voice coil? I need to go dig out the paperwork for that.

how are the subs wired to the amp?

 

[punchme]

The subs are wired to the amp in series

Now I have my 4-channel running my subs and my door speakers . I'm still having the problem at high volume. What is a dmm? and it's only these subs that I'm having a problem with.

Again any help/tips would be most appreciated.

Can someone tell me a little on what dmm is? This problem has been perplexing me. It's got to be a short somewhere...
