Ok guys here's the set up. . .

In the front I have tweeters and 5.25"
In the Rear I have 2 12"
Powered by 1000 watt amp
Indash CD Player

Tweeters are Blaupunkt
5.25" are Bostwicks
12 are MTX 3000
Amp is BOSS Audio
CD Player is Pioneer DEH P4000

After I wired everything in and sure it was grounded properly, I switched it on and it was fine. . .Now if I start my car. . I get this annoying whine from the front speakers. . .and pitch gets higher when I rev it. . .I immediately checked that it's grounded properly. . .and it was. . .I checked the head unit. . and it's grounded fine also

I unhooked the speakers from the amp (5.25") and plugged them str8 into the Head Unit. . .no noise. . . . .

Now I'm thinking that I ran the wire to close to something. . .

I got it running the down the right side of the car. . .

I'm thinking it's the battery cable that runs from the enigne to the trunk giving me interference. . . .

Does anyone agree or disagree. .. .or have suggestions. . . .

Thanks,

PJ
