I have a custom sub box for a 12" sub that fits under the back seat passenger side in a 2002-2008 quad cab ram 1500.
It's a sealed 1.15 cu.ft of airspace made of mdf with a coating of deading material on the outside. I paid $150 a few months ago but decided to build a custom center console ported enclosure so this is sitting in my garage.
Looking to get $100 for the box.
Sub is not included in asking price.
I live in Warren, MI and am selling this for pick up only. When I checked on a shipping price is was upwards of $80 because of the length of the box.
