I have a crunch pzi2250 amp hooked to 2 pyramid 700watt 10's, i just hooked it up today, I've had the amp for quite a while now and never had any problems out of it until now. The amp is getting power but the subs aren't working. i can't figure out why. i know the subs work i connected them to a friends amp and they worked fine. any help would be appreciated.

start by checking your RCAs and remote wire

I went and bought all new rca wires, the remote wire is fine i've checked it several times just to make sure. the amp wouldn't power up without it would it?

just checked the remote wire again, all is fine with it, i just can't figure this out, the amp has been stored inside the house for a couple months now but it was workig fine when i unhooked i, could the cap be part of the problem.

Have ya checked the output(s) on the amp with a dmm?

And no it wouldn't, sorry just got up and didn't quite register till after I typed it

exactly how do i do that, I'm relatively new at checking amps, been hooking them up for years for friends but never really had to check em after that

Read the how to set gains with a dmm in the FAQ threads: http://www.caraudiocentral.net/forums/showthread.php?p=91950#post91950 check using AC Volts 1)probe positive 1) probe negative... and double check your ground... You may have enough of a ground to power it up, but not enough to support it, is it going into protect or just not doing anything?

its, just not doing anything, other than the lights on the amp dimming

It works now, i forgot to scrape away the paint on the ground, thanks for the help.

grounds can do tricky things..
