I will be personally hooking up my subwoofer and amplifier to my Tahoe, I read that there is a grommet under the passenger floorboard that I can run a power wire through but I am having trouble identifying and being able to remove the carpet, if anyone has any tips of tricks, that would be great. I will also be running the remote wire straight to an accessory fuse in the cab itself, will that be successful to turn on the amplifier?
