Horrible Road Noise...

[OoMesKoO 10+ year member]

What can i do to fix it? Ive hooked up a pair of aftermarket 6x9s to an amplifier, and its buzzing like crazy. Ive done all the basics, checked for bad grounds, bad wiring... granted i am running RCAs that arent too great. What about one of those signal noise filters you put between the RCAs from the HU to the amp? Seemed like they should work, just never tried one. Thanks guys!

Better RCA's would help. Shitty RCAs make a ton of noise.

Ive never used the filters, so I can't help you there.

Can you go into more detail about the "buzzing"? Does it vary or change pitch when you rev the engine? Is it a buzzing, or more of a whine? The filters may reduce/eliminate the problem, but they are a band-aid IMO. The problem likely lies within the grounds to the HU or amp(s). Here is a good article on noise though, and how to troubleshoot it:
