View Full Version : Need help with 4th order design

05-08-2013, 09:54 PM
I have a 04 deville and i want to put a 4th order in the trunk with 2 15 inch l7s. I'm new to 4th order designs and i'm not quite sure where to start.
Dimensions I have to work with are:
Depth: 40"
Width: 34"
Height: 16"
Any help would be appreciated.

I'm not set on using the l7s. I would rather go with a different pair of 15s. Anybody have any suggestions?
