I have alternator noise with my xtant amp and I've had a couple of other cheap amps do it. Before when I used a rockford and jbl amp there was no noise and now that I Upgraded to a xtant amp which is twice as much, I get it again. I have the power cables running through the driver side and the rca's running on the passenger side. I was wondering if I changed the wiring to monster would that fix it. or just monster speaker wire. I'm also considering buying one of those boxes to get rid of the alternator sound, but I believe I have it hooked up right so that there shouldn't be any alternator noise. Also do I need a bigger alternator because my music seems to always get louder whenever I turn off my piaa driving lights, I have a .5 rockford cap which should elliminate such problem too. I'm not sure what to do, help.
