I recently hooked up an amp to my door speakers and the are making a whining noise. I bought a ground loop thing and it still whines, any ideas.

Does the whine change as your RPMs change? How are your wires routed through your car? Sometimes, if the big power wire runs with the RCAs, they can pick up interference. The best would be to run both on opposite sides of the car, and if they have to cross, cross at a right angle. try move your RCAs around and see if it improves.

Try a different grounding spot

Ground loops can be a pain in the *** to fix, luckily for you I know a lot about them

Find me on AIM or MSN later and I'll help you out in better detail

nah its not the ground post.

the POWER WIRE is either near ur rca's or ur speaker wire.......separete them!!!!

i just amp-ed my speakers...and i ran the rca on the left side of the center console....power on the right side of the center control.

speaker wires down the sides of the car.

I think he was clipping his inputs (gain too high)

Ahh, i see. I have a bit of alternator whine as well. I'll check my Gains.

Check your grounds as well, I would say it is ground before gain...

my ground seem fine, it was my gain. I dunno how they got turned up so high :-/ I lowered them and it seems alright now. thanks!

I don't understand... aren't you just masking the problem if you turn down your gain? People are talking like the gain IS the problem. You are still picking up alternator whine somewhere, you are just making it harder to hear if you turn down your gain!

Or am I missing something?

Hi folks!

I recently bought a new Pioneer 3600 HU for my ride and I hooked the front output (RCA) to an amp.

The problem is that the HU makes an annoying buzzing sound (not very loud, but still). When I turn off the radio, it goes away.

Any way to make it go away? It's not the type of buzz that changes with my RPM, nor it is a 60hz ground loop (hum).

Thanks!
