My Jeep is a 99 Grand Cherokee with 20 inch Motiv wheels and Nitto tires. I recently installed two Kicker Solo Barics with a custom box which I made myself and added a DVD player with a 7" monitor.
Here is my Jeep with the custom subwoofer box that I built.
The monitor is a Power Acoustic 7" flip down.
I placed the DVD player under the rear seat.
