best 10'' sub for 94 ranger?

i'm looking into putting a ten between my seats in my std cab 94 ranger, so i'm looking for a sub with a relatively small enclosure vol. .65~   dvc and able to handle around 800+ watts rms and 5.5" deep or less...........and hopefully under $250, any ideas?

Look at the M6 series. 800 rms dvc and 5.5 mounting depth. Very nice subs BUT, you will have a hard time finding them for under $250, probably be closer to $350 but im not sure, never priced them from a retailer before so.

And ketel, there are alot of applications where the depth does play a huge factor in what sub a person can get, trust me, i was very limited on what i could put in my wifes truck dues to the depth problem.

I wouldnt recommend a free air for a truck cab. Most freeairs are mounted to a baffle board in the trunk of a car and use the trunk as the enclosure, make sense?

Good thing about a small truck like that, it wont take much at all to make it very loud. Just depends on what you wanting out of this sytem.

so far with the system i have a set of alpine type r components with the type x 6.5 woofer in the door, i'm looking for a sub that can run from around 100 a down to pick up where the 6.5 leave off, no real room for a midbass speaker.  i know i'm very fortunate for the small cab gonna be loud!

with my free air idea i was going to make side board and screw it into the carpet in the back wall so it would be look like it was air tight but it wouldn't be. but i can fiberglass that back of it so its cool,  so now its kind of a toss up between a diamond m5 an idmax v3 or i was thinking eclipse might be good.............the more i get to thinking about it the more i want a dang good woofer plus i've already spent a ton on the other stuff no reason to peter out now.
