The past year i competed in usaci competions. i hit around 145 about. i had 4 sony explodes 12s and the two largest sony amps. this year im trying to upgrade hit bigger numbers. i plan on buying 4 12' diamond m12, i would really like the the tdx, and going to power them with two of the largest phenoix gold tantrum amps. i heard they are really good both the subs and the amps. what is everyones opinion on this combination. my main goal is to hit above a 150 in a 98 4runner..have any advice on what kind of box i should have made for this.

get the tdx 12s. they are nice. you could put all 4 in hooker boxes. Ive personally heard 2 tdx 12s getting 1600w each both in hooker boxes and they sounded very very good.
