Alright so financially i had a plan going for two rl-p 18's walled in my truck.... well that aint happening anytime soon! ran into some trouble! so i want just one 15. a 15 that will get nice and loud off of 1200-1500 rms. what should i get?? i have enough room for a nice 4-5 cubes to work with in the back of my truck so space is not an issue. im just looking for a 15 that will get NASTY loud and shake stuff! shoot out suggestions! also price range will exclude dd's or aq's probably gona pick one up used off here . thanks guys
