would you consider a single sub setup?
a single SX 12 from
www.reaudio.com would work well for rap and rock.. and dont worry about SPL. im sure one 12 is louder than a lot of dual sub setups youve heard
pair of SE 12s would work nicely as well.. although for either RE product you would have to order the other VC config they offer.
sound splinter rl-p 12s
IDMAX 12s..
there are a bunch of subs that would work well.. but whats your budget?
those PG subs are pretty good too from what ive heard
also, nice car man
