I have talked about modifying my supercrewsound box now since I bought it. I have now done it... The difference in sound is unbelieveable. I just used 1/2" MDF to try it as well as just a standard square box add-on. It added approximately .8 cubic ft. more. When I get my permanet subs I should be able to possibly even vent them. The subs I am using now are junk but they are noise and also alot better now. Here is the link to my gallery I set up because I evidentally cannot attach pictures yet.

Can I assume you sealed the add on? That's definitely unique.. If it works, improves sound quality to you, and you don't mind the extra space then good stuff!

 

yes it is sealed..my truck is also a lariat so I have the console that goes from the dash between the seats. When I do a finished product I will blend the box to flow with the console a little.. Well worth the lost room on the floor behind the console for the sound difference.

 

interesting... with that addition on id be careful not to blow your tens....

 

Look forward to seeing the finished pics. Also, what subs are you planning on running?
