Id check the switches on the amp,to see if you have (Full,or HPF switched on)and not LPF,and also switched to 4 ch,not two ch/bridged first,and check the HU/radio settings as well.How did you run your RCAs from your Radio/hu?What HU/Radio do you have?Model/brand

the gain is up lol, i was messing around with all of the switches and nothing happened, and yea i even messed with the settings on my head unit ( panasonic cq-8100u). I have 1 set of rca's from my head unit to my sub amp and another set of rca's to my mids and highs amp, all the rca's are labeled in back of the head unit (sub output, front, rear, aux in,pre amp output) i have my sub out put running to my sub amp and my "pre amp output" running to my mids and highs amp

Try switching the rca's?Where ya get the amp?

i got it from amazon...i know it was a bad idea to buy it from there but it was very cheap

I just checked your HU specs out..you have 3 sets of RCAs..you sure you have them connected tightly at the hu?Didnt come loose/detatched at all??You might even try pushing the Reset button in on the HU for 5-10 seconds sometimes works also..I had a DD Kenwood Lock up on me during an install last year,hit the reset, and came right on and worked fine afterwards.Thought Id done something wrong,You might try that out as well??

May be a reason it was so cheap.Hopefully not but.did you try switching the rca's from the channels that are working to the ones that arent?
