Feedback/white noise, new install.

[guppysb]

Hey there guys, finally installed my audio system today with the help of some friends. Here's the stuff i installed:
Infinity 475a amp
Infinity 9622i speakers
Infinity 6022i speakers, shallow mount
Pioneer 5100UB cd receiver/stereo

When the sound system is turned on, the rear 6x9 speakers give off some little white noise, but when the car accelerates, it increases into a higher pitch sound until the car shifts gear. My friend says it might have something to do with the alternator pushing out more power when accelerating and that is feeding the amp more power. I honestly don't know what it is, but i am open to any suggestions to get rid of the white noise from the rear speakers.

Any help or suggestions on this would be a major life saver, please help if you can and possibly correct my wrong ways.

Edit: Fixed the Antenna relay problem, seems you have to do a 3 way splice, from the receiver's wired remote wire to the antenna relay and also the wired remote to the amp.

Did some research and found out that it is alternator whine like people say and i removed all the rca wires to see if there was any interference or not, seems like it might be a bad ground, think i need to get noise filers.

i am by far no expert but i would check for uninsulated wires contacting the frame. Also make sure you have good grounds.

As for the antenna am 100 speculating here as i have 0 experience with it. BUT it may if it is a simple relay to raise it up make sure it is getting the original current as it was before.

I was looking on sonicelectronix, and they have the Tsunami FL-GL400 ground loop isolaters. I think i need 2 of them, anyone know if they're good or not?

The LAST problem i had with the installation is that the previous harness for the pioneer-2400f that was already installed is a bit small. The pioneer 5100ub is really wide and the the trim wont fit over the unit. Anyone know a good harness?

how did you run your wires? are your rcas ran down beside your power wire?

I am also not an expert, but the white noise is more than likely the ground. Did you sand the paint off of your grounding spot so you are getting direct metal to metal contact? Upgrading your car grounds may help fix the issue. I had the same problem with my 1st gen until I took out the seets and grounded it to the seat bolt after taking a Dremel tool to the body. And like the guy above said, make sure your RCA's are not next to your power wire. They can pick up interference.

You could also try a ground loop isolator on the rcas but that only band aids the problem

try this. Chances are you blew the picco fusses on your Pioneer H/U.

90% of the time it's ground. Rule of thumb, the more ground locations you have in a single vehicle, the higher chance you have for noise like that.

True, but Pioneer H/U's are notorious for the problem that is mentioned in that link I provided.
