Sure, you're sounding good, drowning out the road noise in your Vanagon—but you need some serious kick on the low-end. We've got your solution. This 6" bazooka-style subwoofer will help you complete that kickin' sound system in your rig. We use these in-house, and they're great. We normally mount them in one of two places, either behind the passenger's seat or beneath the rear bench seat. Whatever you choose, you're sure to be pleased.
