I am sick and tired of hearing a lil alternator noise and hissing sounds due to (im guessing) my fricken fm mod. I Have a ps2 and everything hooked up and its super sweet except the interferance im getting. I am a perfectionist and im to the point where im considering selling my cd player and fm mod and getting a good cd player that has the inputs for everything. Right now I have a RF Headunit with two sets of preamps and an equalizer, i also have an amp for my highs and one for my subs running through the equalizer, and the fm mod in the usual location. Im suspecting that the cheap equalizer may be hurting me some also, but even when i have the defeatable button on i still hear it so i may be wrong. Heres where i need help, anyone have any suggestions on how i may fix this problem with my current setup? I tried relocating my fm mod ground already with no luck. Im getting pretty good with all this stuff, but im still a lil new on a few things. If I cant fix this setup, i'll be looking into a new headunit soon. If i do.....ill need to know what i'll need to look for in a headunit that would allow me to hook up a 4 chan amp for my highs, an amp to my subs, an equalizer. Im guessing any with three sets of preamps and an rca input or auxilery input. Am I wrong? Any help is much appreciated.
