'98 Tahoe power wire routing

       I have a 98 tahoe 4d 4wd, I am about to run the power wire and I'm wondering which side will be better to run. I have done driver and passenger sides on friends cars with same type of vehicle. Just wondering if there is a definite better side to do it on.  Also, where is a good place for ground under the rear seat?  If read correct, running a cap you need to ground the cap and the amp seperately right?

Any info is greatly appreciated

I just want to emphasize forbidden's point.  The leading cause of noise in a system is a poor ground.  If you clean the area fully to corrosion free metal, you shouldn't have any problems.  Instead of using an existing bolt, I usually make my own grounds.  What I do is find a good spot under some carpet, then take a sander and sand off the spot I'm grounding too until the metal is nice and shiny.  I then take my ground wire and either crimp or solder on (prefered) a ring terminal.  I then take a self tapping screw and a star washer and drill it into place.  That will give you a solid ground.

If you are using some very heavy awg wire, then if you can try and run a bolt through the bottom of the vehicle where you can attatch a nut to.  Just make sure to sand the paint away first.  That's how I did it in my car (in the spare tire well), and it works great. 

Just be very careful and check underneath to make sure you aren't going to drill into any wiring or the fuel tank.

A tip for running wires on the passenger side of 88-98 Chevy trucks.

The driver's side has a plastic channel for the wires to go into under the sill plate.  If you can find an extra one at the salvage yard or somewhere else, it works great for the passenger's side as well.  Then you don't have to worry about putting screws through your wires while reinstalling the sill plate.
