I probably went against what alot of you would have, done but I went to a few stereo shops on Saturday to see about geting an amp & Sub installed in my 05 DC. Every one wanted to take the console out or tear out something else. So, I opted to just put a box with a sub in it behind the drivers seat. There are only 3 of us that ride in the truck 90% of the time so ot is not in the way, and If I need the room all I have to do unhook two wires and remove the sub box. Here's what I did....I left the stock stereo, speakers, and amp in. I bought a JL Audio 10" Sub in a box, and a Rockford Fosgate Punch P325.1 Amp. Mounted the amp under the drivers seat and the Bass control gain under the dash. What a difference! It sounds awesome. Clear with tons of bass, more than I need really, but I love it. It was a cheaper and less "Tear up the truck" way to go in my opinion. The whole thing cost me under $500.00 installed.
