i just installed the computer and there is static coming from the speakers. it's a really bad whine that gets louder according to the RPMs there's also this pulsing noise that come from the speakers. it's extremely loud. when i unplug the RCAs from the motherboard the noise goes away. and when i plug in my ipod to the RCAs, it plays music fine.
i have an opus 120W psu powered by a 10 gauge power wire. the grounding point is the battery. and i am using an epia m10000. everything is inside the glove box.
i tried searching and i see that most people suggest a ground loop isolator? i'm not sure what this is or what this does. do you guys know what my problem is or a way to diagnose the problem and to figure out a solution? thanks.
hm..i'm using the stock amplifier in my car that's under the passenger seat, so i think it'll be too hard to ground my stock amplifierOriginally Posted by dune
i don't have a headunit. and i'm pretty sure that's not the problem...Originally Posted by Will Albers
I have the same exact problem. A whine that goes with my RPM (my friend thought i installed a supercharger or turbo, lol), and just a crappy noise that kind of pulses for half second over and over.. I dont have an amp, i just have my aftermarket stereo hooked up and i am using the aux input port to hook it to my computer.
if we can find a solution here that would be great..

i'm using a stock amp under the passenger seat. so you're saying i have to take out the seat and cut the ground wire that goes into my amp and ground it at the same point as my power supply? can i just run the ground to the battery? also is this the only solution? because i don't really want to ground my stock amp or cut it or anything. thanksOriginally Posted by viper24
