Hi, I'm gonna install an amp/sub in my 2003 maxima.
From anyone who has installed an amp/sub or speakers. How much power wire did you run? I think I bought 18 feet of the stuff but idk if that is enough.
Does anyone know how much you exactly used?
Thanks!

 

What is the length of the car?

18 feet will be more than enough. Probably do two cars.

 

It depends on where you amp will be. Its nice to have a few extra feet for when moving the box around in the trunk. As long as you have quality power wire then length is not an issue and just get the same, maybe a foot or 2 shorter RCA
