I also want to put sub's in my truck, under my seat (without taking out the gas tank that is about the only place left). But under my passenger (bucket)seat is my disc changer. Do you guys think that a single sub under the driver seat would sound balanced throughout the cab? If not, do you guys have any other ideas of where to put a sub(s) without removing the gastank?

When I had my Extended cab 2003 GMC Sierra, I had one sub underneath the driver's side rear seat and it sounded alright. Bass is non-directional and ... you're the driver, so you should enjoy it more than anyone else :)
