Summary: Crutchfield has a lot of articles with excellent information and that helped me decide this sub. I read the articles, did the calculations and matched this sub to my amp and I am very happy with the sound.
Summary: the mtx terminators are very nice. i just bought 2 12s from a friend and that stuff bumps. i also have a sony xplod and with my 2 12s and my xplod i have in my bedroom i can walk outside in my hallway to stuff falling over on the ground.
Pros: they bump hard and look very good in a nice box
Cons: the mtx terminator amp isnt that great. its a 400 watt and needs to be upgraded
Summary: I have owned at least 10 of theese mtx terminator subs, and i have never had one blow on me, even throwing up to 1000watts rms on 2 in a box. They look clean, are very tough and the spider web coiling makes theese things basically heat proof.
Pros: Lightweight, heat resistant, looks clean. Works well in almost any setup, cheap and efficent
