I got my tc about 8 days ago and I just put 2 12 inch mtx subs in with a mono mtx amp and it was really simple. It was nice how easily the head unit area came out and the factory pioneer cd player still puts out great bass with the subs. I just hooked up an rca converter spliced into the rear speaker wires and it sounds great, no rattling or anything. Also the headlights don't dim at all. the panels in the front pull right out with no screws and then there are 4 screws to get the head unit out. The panels on the driver's side come out very easily as well and there is a wire bracket there to run the power wire etc. The only problem i had was that I had the inside corner panel laying in my friends yard and his dad ran it over with his truck, 38 dollars to replace. lol.
