Those Thunderform enclosures suck.
I looked into the Basslink T before I bought the regular Basslink - It would have fit almost flush with my rear seat in my Accord, but I just preferred the size of the other one. Hopefully it provides a slightly better soundstage than the normal Basslink - there's a discernible difference in bass depending on if you're sitting in the drivers seat or the passenger seat. (Of course, the sub itself will be sitting in the middle of your SUV, so more than likely yea)
All in all you should be pretty happy with the bass response.
