We shelled out dozens and dozens of demos... I can't thank our team and supporting companies enough... We demoed on batt power literally ALL DAY... If you come across anybody that was at the Cali location at Finals, ask them... The only time we had the engine on was to charge up the batts in between demos... Alphard Audio are just studs and make some insane equipment... Taramps 15ks held up like bosses and had zero issues under strenuous conditions... US Alternators have done an amazing job with support and help plus some big boy alts that charge our bank right back up in seconds... JuiceBox for their studly Black Cherries that dished out power throughout the whole day... and lastly our little team in Utah that built a demo rig that does everything we ask it to do... BUT WE WILL RETURN LOUDER NEXT YEAR
