Car Audio Static only when i turn engine on and revv the motor?

Question

Hi everyone, i recently just purchased an upgrade on my headunit the Jensen VM9512, before i had a Sony CDX-GT510. I got the Jensen because i wanted the video screen/dvd player and the 6 channel RCA outs. I have a 15' L7 Kicker playing off of a Kenwood KAC-X401M amp and an Alpine 4 channel MRV-F353 amp. These are playing Kicker KS 2007 model 6 and a half's in the back and 4x6 in the front. Now here's what the problem is, when i turn on the engine in the car i hear a small static and as i revv the engine it grows louder. however this is ONLY when the engine is on, when just the electronics are on i dont hear any static and its perfect. Also, i found that if i only use one set of RCA cables to power the 4 chan amp, and then split it with 2 spliters to fill the 4 channels i hear no static even when the car is on, but i would very much like to not use the splitters seeing as this is why i got the new headunit. Any help would be very much appreciated thanks :)

Answer 2

If you are hearing the noise when you rev up the motor,it might be a bad ground on the amplifier.

Answer 3

there may be a bad voltage regulator. it may make the battery to high. also, the alternator may be making jumps in voltage. try using a separate battery to power the stereo and charge it when you are near an outlet. they make on board chargers that allow you to just hook up an extension cord to the car to charge the battery.
