If what you are looking for are underseat subs then the only game in town is the SWS-8. A real sub under the seat requires a custom enclosure and only if it does not hit the seat rails.
Get a trunk 12W3v3-4 sub, a pair of Jehnerts mid bass drivers and a XD500/3 and call it a day, I would say.
Thanks Technic! Where can one find that enclosure? also, what Jehnert Mid Bass Drivers would be best? Thanks again!
