can i use the bazooka enclosure with a better woofer? has anyone done this i want to use the stock box with a better speaker i like all that space and dont want to go custom to much money thank guys

Yes you can use the stock woofer box for an aftermarket woofer. You'll probably want to make a blockoff plate for the port though (I believe the stock enclosure is ported)... You'll also need to get an external amp to drive your new sub as the stock amp is wimpy...
