Wuw! Head unit going wack.

Alright, i had a post a while ago about my HU making noises while I play the play the cd and the noises sound like I am listening to a bad radio signal. I just read this:

Never just use the oem ground wire for your deck, make sure its grounded to the frame of your car so its at the same ground potential as your amp. If there is any difference between the two that voltage will be on your rca cables and then amplified by your amps.

I was told a while ago that my oem wires for my HU were good enough so I didn't ground my hu to the frame. Do you think this is what is possible causing the noises????

I've used my oem grounds in every car and on every HU I've ever owend , < 6 cars and more head units than I can remember > and I've never had noise problems .

I have been installing car audio for quite a few years and never had a problem with factory grounds, but thats not to say it cant happen, take a digital multimeter and check the ground for resistance with deck unplugged, personally I would unplug your rca`s and see if the noise is still heard, you could be getting RF noise caused by them, is your rca`s and power wire run on same side of vehicle? if so you may be getting RFI from the power wire transfered into Rca`s then boosted by amplifier.
