Whats up F150? I'm hooking up my new amp. I have never used hi input. I have my radio out a bit so I can see the wires behind it. I'm trying to figure out which are the rear speaker wires so I can tap into them at the rear rocker panel by the back doors when you pull up the plastic floor piece. Also which one is the remote power antenna wire?

 

okay...I found the left/driver rear. One wire is brown with yellow stripe, the other is gray with blue stripe. My question is which is negative, which is positive?

 

Radio 12v lt. green/purple + radio harness
Radio Ground black and black/lt. green - radio harness
Radio Ignition pink/black or lt. green/yellow + radio harness
Radio Illumination lt. blue/red (dimmer) + radio harness
Factory Amp Turn-on dk. green/purple + radio harness
Notes: This is the subwoofer amplifier turn on lead. The subwoofer and amp are in the driver side rear corner of the cabin. The subwoofer speaker wires are brown/orange (+), and red/black (-) at the radio harness.
Power Antenna N/A
LF Speaker +/- orange/lt. grn - lt. blue/wht +,- radio harness
RF Speaker +/- white/lt. grn - dk. green/org +,- radio harness
LR Speaker +/- gray/lt. blue - tan/yellow +,- radio harness
RR Speaker +/- orange/red - brown/pink +,- radio harness


Does that help you any?

 

Awesome brother! That helps greatly! Which wire do I hook into for remote power?

 

Even though I do not have a factory amp, I have the dark green/purple wire. Is this what I should tap into for remote power?

 

That would be my guess

 

I got tired last night and turned in after I ran the 4guage constant power. I guess I'll drill a spot in the floor pan to bring it in. I wanted to run it in one of those slits under the plastic molding where the factory wire bundle is but it's too big.

 

So for instance, RR orange with red stripe is negative???

 

yes RR ( right rear) orange/red trace is negative, and your 4 gauge will fit in the channel with the factory wiring bundle, I know because I have 2 gauge ran there.
