J From Nebrask
I bought 3 of these subs and stuffed them into a Ground Shaker 3 chamber vented enclosure for my '88 Suburban. Running a TMA 1000.1 amp and just hit 141 db at a sound off this past weekend. I'm happy with the out come, however, I will be upgrading my amp to possibly get just a little more "umph" from my subs... the set up does hurt my wife's ears, but kickstarts my cardioarythmia regular again... lol

sealed box 1.25 cu. ft.. loose poly.. powered by 500/1.. break in took about 20 playing hours.. sound quality is off the charts.. hits all the notes.. very loud for only 300rms.. the best sub i ever had.. buy with complete confidence..
