maybe your sub(s) is not wired to the right ohms?

as far as i know they are right cause i had them wired for a one ohm load on the last amp realy all i did was take out one amp and put in a fuse in line off the second battery and the new amp and now i dont have alot of output

ok guys i know i have been posting alot about this but i just went and tried the gain setting witht he tutorial and i think the amp is funked up.... i unhooked the speakers turn all the stuff flat on the cd player and put in the 50hz tone and put the DMM on 200 acv and put the probes on the terminals and the most i got out of the amp at the terminals was 0.00 with no gain and i could turn the gain all the way up and the most i got was .5

u sure it's not the DMM?

Can you drop another amp in its place, and see if that works fine?

pretty **** sure

cause like i said i dont get alot of output regaurdless how much the gain goes up

It should wang rediculous.

Ohm out your subs with a DMM, set your gain with DMM... then adjust +/- a little by ear.

checked the subs there sitting at 1 ohm.....tried setting the gain with the tutorial on here and the most i can get the gain to get up to on the DMM is 6.4....i also checked the remote and im getting 13.4 there and i also recleaned up the ground too and thats just fine as well

Do you have it on AC voltage? And the correct range?

Its nothing with your multimeter, since you put in another amp and it worked fine.

Talk to the seller and to IA, see what you can do.

He contacted me about it, and I have talked with Nick at IA. Luckily I fully insure every product that I ship.

well, if you put it another amp and it works fine. That means your speaker wiring is done correctly. Whats your ohm load after box rise?So your amp (20.1) turns on and everything, right? Then, i would say it's the amp, but that's an insane amp!
