Aight I have two 15inch subs audio bahn with a box and ported. This system was in my old S10. Now exactly what would it take to put these two subs with out filling out my entire back extend cab. I was thinking maybe make a slip seat or maybe a slip seat from a different year model. Here is the box and speakers. If I have to make another box that no big deal.

 

throw that crap away.

Ummmm....two 15's with some decent airspace while keeping a back seat...Probably not gonna happen in an old style ext. cab. Unless you make a tall box to sit on the floor where the 60 section of the back seat WAS and only have the 40 section. About the only way I can think of.
Or ditch the back seat totaly and make a box that acts as a seat too. Only way I was able to fit anything decent with the right amount of space in my 99 ext cab.



^^^ That is 2 cubes even tuned to 29 Hz for one 12". Took up just as much space as the original back seat. With some work and time you could make it look nice and be comfy, I wasnt ever the unlucky b@stard that had to sit back there though

Im not sure what your talking about by 'slip seat'.

 

Bart great idea with the box being a seat. I think im gonna do that. Thanks

 

Yep yep.

If you ever decide to step it down to one 12 ported...I have a box for you then
