Why does my stereo make weird noises with the subs

Question

I have a Sony CDX-F5000 in my car, and I just got a 3200 watt hifonics amp, and 2 kicker l7's, and when i change the radio station, or the song on the cd, the subs make BOOM noise and i can like hear them making random noises when its reading the cd or song before it starts playing.

Ive tried re wiring the stereo, thought it wasnt properly grounded or something but it is, and it still does it.

Is this from positioning of the wires or what?

Thanks for any help guys!

Answer 1

Whenever there is a hard thump while changing stations or a heartbeat or even a low to high sound coming out of your subs its due to the sound and power conflicting. RCA wires are either conflicting with your amp power wire or your car wire harness. This problem can be easily fixed by either buying an expensive highly insulated RCA wire or wiring the RCA & power/car wire harness on seperate sides of the car.(run the power wire on the same side of the battery, run the RCA on the other side)

Yes. also double check that your RCA's didnt get punctured in anyway and are secure on both the Radio & amp.

Answer 2

Big Tim is Right, the Power and RCA should be on the opposite sides of each other. When i hooked up my system i put the power on the left which is where the battery is and i ran the RCA across the right side. its more work but it keeps the quality of sound pretty good.
