Description:

Hey guys,

I have a custom box made to fit flush in the back of w204/c63's. The box is made from fiberboard, I will post pictures below and you can see how the design supports the beam across the back as well as the hump of the trunk at the bottom.

Along with the box I am selling my 12" Rockford Fosgate P3D4-12 Punch P3 and my amp that goes along with it a Pioneer GM-D7500M Car Amplifier. I will post link below of the items which will provide more details.

Here is a video of the sub:
