I JUST got done having all of this done in my Mega Cab and it sounds amazing. I opted to not have the steering wheel controls either. It was too much more money to have something I never used anyway. The only speakers I kept stock were the ones in the dash and they are handling the extra power nicely. If you are interested I can get you the details on what I had done. The box I have still leaves a ton of room for storage too. Just one sub but the flow of air in the box makes it sound SICK! Have you ever checked out the Kenwood Excelon series? They are like half off retail right now and they come with a higher power output by far and they have an unsurpassed sound quality to them.
