i have a 2006 ext cab , and i have an mdf carpeted bow with the subs fireing tward the back of the front seats, and i hate the vibrations i get with that box. if someone is sitting in the back seat their is no vibration. So the box need weight on it to not vibrate. is their something wrong with the box, i just dont know. any sugestions on what to do would help alot thanks

 

Does the seat actually rest on the box itself?
