I loaded this puppy up with 2 Alpine S 10” subs with a probably underpowered amplifier. The fit and sound of this box absolutely blows me away. I’ve been in “extended cab” trucks for the past 13 years and never thought I would be able to get this level of subwoofer performance with these types of trucks that have such a small storage area. If you’re thinking about buying one, go ahead and swipe the card - you won’t regret it.
