new speakers, new amp, sounds horrible.

So you suggest i get a different head unit?

once a pioneer has noise issues then it will never go away. depending on what you do to fix it it might get better to the point where you can stand it or barely hear it but it will alway be there. if you can get it warrantied then i would do it but theres no garauntee that it wont do the same thing.

So what brands do you suggest?

Thank you very much for that link. Are the yellow wires called amp fuzes? If so, where can I purchase these?

And this will take away the noise from the alternator coming through my speakers??

If you performed the test at the top of the page and determined that there is no electrical connection between the shield of the RCA and the chassis of the radio, then yes it will fix your problem.

Ok thank you very much

Hello, I just recently installed some polk audio 6.5 inch component speakers in the front of my car and then hooked the speakers to a 4 channel alpine digital amplifier and the instruments sound up to par but the singers voice it much lower than the instruments so you can barely hear the singer. Any Suggestions? I also have a pioneer stereo. Thanks in advance.
