I have run JL subs in db drag racing for a few years and my suggestion is ti use slot ports they sound much better with that brand however if you have the bucks buy the new w7 that was just released 700 bucks or the new kicker L7 that is much improved but as far as amps I would recomend the concept 2500d or the lanzar vibe 1200d concept is 6-800bucks the lanzar is 3-400 bucks either amp with either sub will blow your mind in a tour let me know you budget
