noise bleed over into passenger speakers

[etlsport]

my rca's are ran on the driver side and my power wire is on the passenger side
for my amp ground, i am using one of the bolts that secure tie downs to the frame in the back
the polarity is correct on all of the wiring as well...

the only thing i can think of is that the power wire is ran along side of the speaker wiring for the passenger door...

try re-routing the speaker wire to the passenger door.. take it down the middle of the passenger seat and across the floor board, then straight across under the carpet to the door... i had to do that with my RCA wires.. out from the head unit into the passenger foot well.. down the center of the seat and out to the amp
