you will need to do some research on that yourself. figure out what the box specs are and look for a sub that works in it that is within your budget.
I have been doing some research and have come up with a couple of different brands.I figured someone else may have one of the boxes also and may know what worked well in it.It is the downfire ext.cab enclosure
One of my favorite woofers for small boxes is the Earthquake SWS series woofers. These woofers work well in small boxes and they work very well in a downfire configuration
