JL Audio 15" subwoofer question

I was searching for some subs for sale online to get an idea of the price
range. Now audio wanted 375 for one 15" 15W3. I was wondering what's the
difference in the models and how the perform from each other. I'm asking
because I havent found a place yet that has these subs and an amp working at
the same time, and I cant listen to them for myself, i'm all bad luck at the
moment. The subs are . . .

JL Audio
15W3
15W3 d2
15W3 d4
10W0

I was wondering what's the best of these models and how they perform to each
other. I was looking at getting the 15W3's but I found a great deal on a
pair of 15W3 d2's. How do these rate to the 15W3's? I just found out that
i'm getting a truck i'm trading in my camaro. Would these be too much for
that truck for me to handle with such small space in the cab? I could deal
with it but people with first hand experience are the best and what i'm
looking for.

Thanks for the time.
