So your truck has the horsepower and the suspension lift, but does it have the bass? If you're wondering what to do with all the extra room in the rear cab, may we suggest a 40,000-watt car stereo system similar to what you see in this video? Granted, the hair-raising stereo system might be just a little (ok, a LOT) over the top, but it should serve as some inspiration for all you trucking audiophiles out there.
