standard HU wiring:

Yellow - goes to a const 12V source
red - goes to a switched 12V source (only comes on when the key is on)
black - goes to ground
blue - raise antenna when RADIO (not CD) is turned on
blu w/white stripe - amp rem, turns on amp when headunit is on

on the amp:
pwr - goes straight to battery (remember to use a fuse close to the battery)
gnd - goes to a pl;ace on the chassis close to the amp. remeber to crape away all the paint and dirt
rem - the blue/white wire from the headunit connects to here

RCA's - if this is a bass amp, it will go to the RCA's on the back of the headunit that says sub. Remember that you might have to turn on the sub output on the HU.
