Mainly looking for a small sub to go under the rear bench in my 97 extended cab if anyone knows of a box out there or has one I could buy that would be great! Don't really want to raise the seat if I don't have to .

 

This really depends on what you want to put under there. Do you want a single eight in a powered enclosure or a downfiring ten in a custom box with an external amp?

 

Just want bass I have alpine speakers that have very little bass in them...

 

Running an amp to your speakers will help

 

I have an 8" kicker under my rear seat. It sticks out a little bit but not to bad, I've thought about cutting it and making it a bit smaller and making it a ported box. It's hooked up to a JL 250w amp, and hits surprisingly hard for an 8.

 

I used to have 2 kicker 8's under my seat, they hit pretty good especially for 8's and fit very nicely in a box I made. Now I'm pounding on 2 JL 10's which leave no extra room but are way louder and clearer.

 

Im running a Rockford shallow mount ten on an 1100 watt amp and it does everything I need it to do.

 

I run an audio pipe 10 under my console. Nice alternative to under the back seat
