That he did.

 

I know this thread is old, but if you absolutely need 4 subs, why not go with four 8s? You could do a seat lift and drop 4 W7 8's in a custom box... That would be legit.

 

How about four Kicker L7 eights?

 

I have a custom ported box with 2 10" RE SE 10's tuned to 32hz. Carpeted light grey to match the interior of my 07 f150. I also have a LMI welding 1.5" seat lift.( don't even notice the lift) I think I have some pics in my profile/garage if not I'll get some. I'll sell the box,subs,and lift if interested.
It's time to change it up again.

 

Two tw5 would be loud and enough bass

 

Whats the problem with a seat-lift?
