i have been wanting to put a system in my 2001 gmc sierra, but i dont want to spend too much money on it. ive considered installing a 12" bazooka, but im really not too sure if thats the way to go yet, ive have heard them before and i think that they sound pretty good for a woofer thats already pre amped, but this was on a chevy cavalier. does anyone have any suggestions or information that i may use to make my decision, and also does anyone know how to install it if everything in my truck is custom so i pretty much need all the wires and whatnot.
