My question is if you guys have ever seen or done a ID Max 12'' with 9'' Mounting depth in a 1500 ext. cab truck. Do you have any idea's of how to fit it in there or not? If so, you could e-mail them to me or I will check back here just to see. I was thinking you could put the box underneath the back seat behind the driver and have the sub fire towards the driver....You think that would work?
