2009 4dr. LB Speaker Wiring Question

[AutoXBot]

I just wired my 2009 4dr LB with some new Polk audio DB651s speakers. I refered to the notes from the sticky post in this forum:


"LF Speaker +/- pink - purple +,- radio harness
RF Speaker +/- gray - blue +,- radio harness
LR Speaker +/- red - white +,- radio harness
RR Speaker +/- red - white +,- radio harness"

I used some Raptor 16 gauge speakers wires from Autozone. It had two colored wires - 1 red, 1 clear. The red had copper inside, so I'm thinking this is the positive and the clear one has aluminum wiring (for ground)?

Just want to make sure I soldered the right wires together correctly:

LF speaker: pink wire to red speaker wire, purple wire to clear wire.
RF speaker: gray wire to red speaker wire, blue wire to clear wire.
LR speaker: red wire to red speaker wire, white wire to clear wire.
RR speaker: red wire to red speaker wire, white wire to clear wire.

Thanks for the help/input guys!!!
