if you are running 12 gauge power to your bazooka tube then you are GRAVELY underpowering the tube (i have one in my rabbit it rocks). You need to start over with
at least 8 gauge wire and I would say to go for 4 gauge for better power management.
I have 4 gauge running to a
distro block and then splitting it off to 2 seperate connections. if you are just running the bazooka and another small amp i would say go for a distro block like
this that will accept your 4 gauge and split off to two 8 gauge connections. This way you are not under powering your amps, they are not getting hot and ur not popping fuses like a skinny blond popping E at the local Rave.
