I'm getting the dreaded grounding noise problem coming through my speakers.

Will grounding my line converter (line to RCA) fix that problem or should I look for a different ground for my amp?

what amp do you have if its a cheap amp you can get noise from that. your ground wire might be to long so shorten it also it can be cheap rca cables or you can have bad hi to low converters. if you don't want to check all of those thing just buy a noise filter that might fit the problem.

Thanks for the suggestions. I'm running a MB Quart 4200, and my ground wire from my amp is about 18" long and it's on a pretty good spot, unpainted metal.

I'll check out buying a noise filter and see if that works.

What else do you have installed?

Noise filters are a waste of money. Do you have power wires and RCAs in close proximity?

I have the same amp, and I had the same problem. My installer connected a Ground loop isolator and it solved the problem. However, we relocated the amp, and I have a faint high pitch noise from the speakers. The amp was moved closer to the battery, we might have to relocated it again.

I have the MB Quart 4200 going to my fronts and rears, a sh!tty Sony Xplode amp going to my HK subs, Alpine MP3 changer and that's all. Both amps are grounded to bare metal, but the Hi-lo wire converter isn't grounded.

I have my speaker wires, RCA cables and power wires all separated with cable ties and flex loom.

Just for fun, here's a pic of my amp install, without the speaker wires...

i had a similar problem but i dont think it was from the speaker. try grounding the metal shields on the RCA, that reduced the noise to an acceptable level.

You might want to try grounding you HU where your amps are grounded at.

If you are using the OEM HU, sometimes the balanced output of the HU will cause noise if the amp is not made to accept a balanced input. I think that it is highly unlikely that the Sony Xplod amp has balanced inputs.

Grounding the metal shield might not always be a good thing.

Do you have a Ground Loop Isolator from your RCA Jacks to your amp? If you don't, try using one. That should take care of the problem. Also, I see your amp is kind of close to a power source (your battery), try relocating.
