this is my first time on this forum and questions like this would lead to arguing and fighting on many forums ive been apart of so thats what i was trying to stay away from on this thread, thats all i was trying to say, but im glad yaw found humor in it...And i didnt make that question clear enough that i was askin, im thinking about walling out the back and want to have some subs that will hit my lows like no other, im sure the top 3 subs on the market that yaw stated are fairly close....whatever i put in my tahoe next it will be tuned between 30-34htz but i just want a sub that will hit HARD and still be able to change frequencies as much as possible from an 18
