The Neo-Pod fits all 4-door '07-'17 JK Unlimited Wranglers and houses an 8" shallow-mount subwoofer to fill in that low-end audio void! The pod easily slips under the passenger seat for a factory and stealthy appearance and there's no need to remove the seat for installation. Specialty screws easily attach the pod to the floor and black screw caps complete the look. Bass output is maximized because the sub fires downward, hovering just above the floor. If you have custom-fit rubber floor mats, the rear mat can rest slightly on the back of the pod without issue. The Neo-Pod can be integrated into both factory and upgraded systems. Even if you have the factory subwoofer, the Neo-Pod can be added for additional bass. For those looking to add some bass while keeping their factory system intact, the Neo-Pod can gain the complete signal from the factory sound bar speaker wires. There is a very easy place to tap into those wires along the floor, under the trim, by the passenger seat. The signal from those wires is then used to power an amplifier which can reside under the driver seat. So the Neo-Pod's under one seat, the amp's under the other, and no cargo space is taken from anywhere in the vehicle! Most '11-'17 Wrangler Unlimited models have a small metal bracket attached to the seat riser with two screws and the bracket has one or more wire plugs mounted to it. After removing the bracket, the plugs are easily relocated to the seat frame as shown in the installation instructions. (They pop right into some existing seat frame holes exactly like they popped into the factory bracket - super easy!) Any other wiring that's connected to the passenger seat is also easily relocated and explained in the instructions with plenty of photos for illustration purposes. Clearing the way for the Neo-Pod is really easy! The Neo-Pod has an internal sealed volume of .375 cubic feet and an 8" shallow-mount subwoofer maximum mounting depth of 2-7/8". Pod sidewalls are an impressive .25" thick, nullifying any vibration. The Neo-Pod will not fit 2-door JK Wranglers because the seat frame and riser is different, allowing the seat to tilt forward, but leaving no room for the pod.
