Ok, i have my car completely wired up, power, RCA's, Remote, and Ground. I have the Subwoofer setting turned to ON on the deck. I have the subs wired to 4 ohms. Subwoofer level (+ from first sub going to amp, - on first sub going to the + on the second sub, and the - on the second sub going to the amp) so its wired to 4 ohms. The amp green power light turns on. Apparently my head unit has 4v pre outs, if that changes anything? They dont do anything.... what in the world is wrong..... the amp cant be fried cuz the fuse next to the battery was completely fine.... What am i doing wrong... someone please help....
