I bought this for my 03 Silverado Crewcab and it fits and matches perfectly. You never see it and most passengers are surprised when I crank it up. As for sound quality, it depends on the person. I am a bit on the young side (23) and I find that there isn't enough bass in certain situations. Windows up cruising around it does quite well but if you are expecting it to rattle you license plate you won't be impressed. It still puts out good bass and is neat and clean in the cab. For the price, if you are obsessed with the truck looking stock and keeping the ability to fold the seats down, this is the thunderform for you. If the stock look isn't as big of a deal, I'd recommend buying a enclosure and outfitting it yourself as you see fit. You will get much more bass but will have to sacrifice space to fit an external amp.
