update: some reason the sub would cut in and out ant any time, any volume 5 trips latter and many talks with other installers and bazooka and kicker co, bazooka sent a replacement amp, with auto on/off ( as kicker has on the 8and 10" powered box) after they removed the wire to fuse box, and only have pos w/fuse to battery and the ground, 6 days it works (so far) great , a # of people said each year they change computer ?? and the new one,(they say) searches for a miss in the system, and that connect to fuse box was it?) who knows ?? anyway you think for $42,000 why not just add the powered sub ( option $650) to them with the 8" touch screen?? it now sounds 100% better with just that little kick from the bazooka.
