ive been through alot of subs kickers and mtx but my logics i got from a pawn shop and i also got a 1600 watt logic amp which i had untill i sold my car they were the best speekers i had ever had.

loud, lasts, and cheap

it is only a single voice coil at 4 ohms

i have had these subs for a long time and i don't know what it is about them, but they just can't seem to ever give up. i have had these subs for over three years and i have been pushing 1600 watts to both. they are absolutely no treo, and don't have the best sound quality, but they are not bad either. if you do push enough watts to them with your amp tuned to the right impudence level, they will make even really high quality subs nervous. they do put out very loud and it was a good choice for me. be that i bought them for 150 bucks both in a box brand new, i have no room to complain. i now have treo's but i would recommend this if you don't have money growing on tree's. great buy.
