Here is the most awesome JackHammer demo crate built ... yet :) A JackHammer in a Hummer ... they were made for each other :) JJ Hifi's achievement is truly amazing. This is the level of the Alpine crates at CES in LasVegas !!!
Except that he did it in a month! Well done.
Nothing was left to chance. an exceptional body, 24 "rims, 14m2 of soundproofing material ... 8 Optima batteries ... 7 large amplifiers ... 1 square JackHammer .... 8 pairs of HP T8000 kit and 6 square T8000 series subs 25cm. This is for the next Motorhead concert ...;)
