I am looking for someone that has this truck to find out what system you put in it I get so many different people telling me what I can and cant put in my truck, I just want it to hit hella hard. I prefer 12's
There are boxes that fit under the fold-up seat in the back.
One is a removable pre-manufactured box that clears the driveshaft hump in the center.
Another is a pre-manufactured bolt-down box that gets mounted to the bottom of your seats. They come in separate pieces.
For best performance you will need to make a custom box. You may end up installing it in the bed. This setup will allow you to use any size woofer and box type/size. The only drawback is having in in the bed.
