I have a problem with background noise when i first turn on my head unit, turning on dome light, and also when i switch a track. I have the RCA's separate from the power cable so what could be the problem?
Thanks for your help Carlos, but I just figured out the problem. I think the amp i was using was a pile. I bought it off ebay for 100 bucks hoping it would work. Its a kenwood 20hm/4 ohm stable built in crossover 600 total watts. Anyways, the subs wouldnt hit very hard at all and you could hear music in the subs not just bass. I know that aint good so i hooked them up to a small pioneer amp I had. Only like 200 watts. They pounded 3-4 times harder than with the kenwood 600w. So now i know it was just a POS.
Yup hes right probably a the ground, you said you had kenwood amp that was 600watts? Is it the kac-729s, if so I have that same and have no problems with. I made sure the ground was put on correctly and the other wires were also correctly installed.
