Yea four 8 is like two 15s!? I'm just saying like two in the right size box vs four in the wrong size box.

NO, NO, NO : 4 8s are not like 2 15s !
Surface (cone) area : PI x R²

So 4 8s => 4 x PI x 4² = 201.06 sq inches

2 15s => 2 x PI x 7.5² = 353.4 sq inches  Totally different, quite the double.

If you're trying to raise the seats, you should do 10" or 12" subs. They will perform much better than 8s, even sealed.

A single 10" ported can do the trick, if you don't want to spend a lot.

 

For mids and highs, just do a 2 way upfront : it will be much easier, and can sound veeeeery good too !

So as far as mids and highs go what about two Rockford fosgate pro tweets and four 6.5 pro mids? Any other suggestions?

I put 3 10s in a co-workers 15 silverado double cab, sundown SD310 shallows on a SCV2000, shit slammed pretty good, where are you located? he sold the truck and is selling them.. 

BTW we did raise the seat with 3/4" mdf spacer on each stud
