I am Installing a sub and amp in my nnbs rcsb and am wondering how you ran the power wire into the cab. Somewhere through the fire wall or under along the frame to the back of the cab? Any help is greatly appreciated!


I also posted this in the GM specific forum as well but wasn't sure if I would get more help here.

 

I had mine done at a local shop not too long ago. He connected the power wire to the fuse holder that is on the firewall close to the battery. Then he ran it into the cab (drivers side) alongside the main bundle.

 

shood be like most cars or trucks
they got a rubber plug that also holds certain wire harnesses that you can plow that power wire into and run it into the engine bay

 

there should be a rubber gromet underneath the dash by the pedals that you can fish it through if not drill a hole with a stepper & go buy a gromet from lowes or home depot have fun!
