Current build of my arm-mounted bass cannon for my DJ-Pon3 cosplay (again) at BUCK Convention later in August. Ordered a bigger and (hopefully louder) speaker for MORE POWER, which should arrive in time, i hope. Speaker on the current build is a HMDX Jam Yes, those lights are sound activated. I apologize for shite video quality, I need a better camera. Song - Megaboy by Savant
