lights are dimming with no amp? lol check your battery connections and alternator connections and grounds. Most likely loose or corroded.
ya, that shouldn't happen. I'll bet that you have a lot of corrosion on your battery terminals. You should never have dimming problems with basically a stock system.
ah, you took the words out of my mouth, i have had severe dimming of my dash/dome lights with just an eclipse deck wired to the stock harness....way too much drain for the tiny stock wires, i hardwired it with an inline fuse and it was ok after that
