Well, mine is a work truck so it won't be getting amps or subs. I did remove the stock radio from the dash to make room for my aftermarket deck. I didn't remove the OEM deck, I just moved it shelf in the back of the truck. It's still connected, I need it to run the warning/signal chimes through the left front speaker. I think it will even generate a RAP lead for the new deck, as it has provisions for an amplified antenna lead fed from the deck.

I'm saving about $140 bucks by keeping the old deck and not buying the replacement module....
