Alright need know some lengths for...

Power cable (coming in on Drivers Side)
RCA's (going under the console and under the back seat into trunk)
Speaker wire (same as RCA's also coming from both doors and rear speakers)

It would be helpful if someone could give me some estimated lengths.

grab a measuring tape..lol...it'll all depend on where youre installing everything

Just remember always add a little extra to your length. It would suck to wind up not getting enough.

exactly...i added an extra two feet from my measurements just to be on the safe side

get an installation kit, they've got all the wires you need, and they're generally the right length...mine were just perfect.

oh...and your grounding wire for your amp technically shouldn't be any longer than 18"
