I have a single 10 inch in the back of my truck behind the passenger side seat. Keep in mind that with any behind-the-seat sub you will not be able to use the storage underneath the seats for things like tow straps, first aid kits, tie-downs and bootleg midget ****.

Also from a sound quality point of view a single sub behind the driver side seat can only have about .35-.40cu ft of volume to work with which is FAR below optimal for most subs. Alpine recommends a minimum of .6 cu ft for their 10" models. Shallow mount subs may work with this restriction but do your research. Going to a box that is too small will destroy your low-end and eat up power.

 

what if i just got a single box for behind the passenger and a single one behind the drivers rear?

 

Yeah, I wish I could of put it behind the seat, but I had already got the subs. I think the increased air space of the box makes it sound better, but I keep absent-mindedly putting my elbow there while driving, and nothings there.. Oh well, good luck.

 

so does anyone know of someone that is running a like brand boxlike kicker or whatever for behind the drivers rearseat?

i think im going to get this biker ahoy
