On mine IIRC, I used a 17 foot wire from battery to trunk well. And had about a foot extra. To be safe I'd go 18-20 and just cut it after you run it to your desired location.

I always ended up using the pre-packaged kits and while they range between 17-20 feet, I always had more than enough to get the job done. What are you looking to put in for amplifiers and what guage are you going to be running?

Re: Power wire?
Make sure the wire is big enough to supply the juice your amp will need. You should look at MINIMUM 4ga.....but bigger IS better.
..also make sure to do the BIG 3 upgrade.
