I have some questions for all y'all that know more about audio. I wanna but a sub and amp under my rear seat so I can still haul people around. H fortunately I have an odd configuration where the seat flips forward to create a load floor. I have 6" under the seat without any modification. So is this enough depth to fit a good sub underneath as is? I have pictures for reference if that helps. Any input is appreciated

 

Lots of good subs have mounting depths of less that 5-6 inches. I think the configuration of your back set is the same height and dimensions as the ones that fold up, minus the mounting brackets. What size subs are you looking at? A set of Alpine Type R 8's would handle 700 watts and be an easy fit.

 

They make plenty of shallow subs/boxes made specifically for that application. Or you can always make your own box...

 

ideally i was thinking a single ten, but i have though about a set of shallow 8s

 

You probably wouldn't even need a shallow 8". Full size subs typically have better performance and life.

 

I had a set of kicked comp 8's. Regular mounting depth that's only like 4-1/4 inches. In my sealed box they sounded great.

 

Nice, I may have to see what the mounting depth on a 10 gonna be

 

does anyone know how much room needs to be left in between the top of the of the sub and the bottom of the seat?

 

More than the excursion of the sub, (xmax)

 

where do i find xmax? im seeing most 10s have a mounting depts 5in or less
