Hey, i just got my system almost satisfactory. I am still gettting a little noise. I gave up on the noise from my h/u through the rca's and got the converter thing that gets the input from the h/u output wires. Hey it works. I am still getting engine noise in my woofers though. The woofer amp and the mids/highs amp share power and have same ground but in different places. It might be my weird h/u. Dont laugh, but its a sound storm. A few facts about it: It wont come on unless the antena is conected, the metal on the h/u will spark when it touches the metal that holds in place, It skips easy( bumps, hit breaks hard sometimes(worse when its cold), when bass hits hard in cold wheather). Any advise besides get a new one would be helpfull. Also, i have 2 12" kicker cvr's dvc pushed by the 1500D prestige mono 1000watt 2 ohm stable amp. The speakers are wired in series and i was wondering how else i could wire them and not hurt the amp. Thanks!!!
