Car Audio Questions

[00_slow_5spd_ls]

Hey guys. I am currently running a
Pioneer DEH 6700MP

Connected to an Alpine MRPF-350 which is capable of 350 watts rms @ 2ohms.

currently connected to my JL Audio W3 DVC that is blown.

I will be buying a 10" Alpine Type R dual 4 ohm voice coil (so I can wire it at 2 ohms)

I also have an Alpine MRPF-240

It is a 4ch amp currently connected to my two MB Quart DTC 6x9`s giving them 50 watts rms. (mounted in the stock sub spots)

I have a pair of 4" Pioneer TS-G1041R that6 i have no yet hooked up.

I`m going to buy the pioneer ipod interface and install it so I figured I would rewire my whole system.
Where do you guys have your ground.
Should i ground both amps to the same grounding point.
Should I ground my head unit (I currently have the factory to after market wiring harness).
I'm going to buy a new wiring kit and RCA cables because I have annoying whine.
I am also going to reinstall my stock 6x8 sub enclosure so my speaker box can fit snug.

Best place for ground is the shortest distance from the amp. (Make sure it is free of any paint, and that the ground wire is = size of power wire) Secure the ground well.

Yes, ground them at the same place.

Not neccessary to ground head unit when using a wire harness.

Be careful about the kit and RCA's they may not help your engine noise at all. Usually the cause for engine noise has to do with your ground. Make sure you do the above things with the ground wire first. Also make sure your RCA's are ran on different sides of the vehichle than your power wire. If you still have noise try running a 16-12 gauge ground wire from the ground terminal on the amp to the ground wire on the harness of the radio. Hope this helps.
