  1. Worth the money

    Posted by Unknown on 5th Jun 2014

    The box looked well built when I received it. It comes with a terminal port you have to install, what they don't tell you is they have a hole drilled out , but carpet is covering it . I almost drilled my own hole which would of been bad. Overall sounds good and fits well. Feet may hit the box when getting into the truck on the box side . Takes 5 days to build and another 5 days to ship

We build each sub box and ship within 3-10 business days excluding weekends.
