Default Engine Noise :(

Ok.. So I've been fighting with Engine noise for the past week. I added 2 amps and a MTX RE-Q to my factory Bose w/ Nav.

Equipment:
RF Punch 600a4
RF Punch 250.1
MTX RE-Q
RCA Tsunami 4 Ch Shielded Cable
Speaker Cable: Stinger 9 Conductor Speedwire

Power & Grounds on Right Side of Car
Speaker wires on Left Side (RCAs no where near any of them)

I grounded the amps and RE-Q to the bolt that sticks out of the car where the factory amp was mounted. I bought a Multi-Meter but haven't a clue how to use it to check the ground. (But I really don't think it's my ground)

I have 4 awg Power cable to a distribution block that goes into 8 awg for each amp and the RE-Q is connected to that block as well.

The Remote Turn on is coming from the lighter outlet under the glove box because the Bose Remote wire isn't strong enough to power on 2 amps. I am not using the factory harness for grounds or power.

So Far:
1. RCAs connected to the amp disconnected from the RE-Q no engine noise at all.
2. Connect the RE-Q back up and it's there. It gets worse when i turn the gains up on the RE-Q.

The stereo sounds really good with the engine off or turned up 50% with the engine on but when turned down the noise is going to drive me nuts.

Has anyone else had expierence with the Re-Q and engine noise? I'm going to try to hook up a passive in-line converter tonight to see if goes away. I also moved the RE-Q a few times and I noticed it gets better and worse depending on it's location.

Also there's a sheild cable included on the stock harness. that connects to the bose subwoofer. I'm wondering if that had something to do with reomoving noise on the stock system. Any ideas about that?

If anyone has any tricks that might help it would be appreciated. I'm tempting to get the RF 360.2 or Audiocontrol Line Output converter but i hate to throw money at this and it not fix the problem.

Any help or suggestions would be appreciated.

Thanks,
Weapon
