I have 2 18xl's on an 40.1 incrimnator audio amp at .5 now im looking for a big big upgrade my freind is telling me go 4 15xl's with another 40.1 or just a dc 12k, now are there any other 4 15 setups u guys would recommend I saw the RD heavyweights look like some ****** subs but im unsure, or I was thinking of 4 15inch lanzar opti drives on the 40.1 but i dont think i would see any upgrade there. so what you guys think? this is in a 03 tahoe subs firing up port to the rear
