here r the pic's of the finished product. still need more time testing, but not in the mood right now. got 16hrs last time with batts not dying, so i'm happy for now, but now that the batteries got cycled, i will run it hard for my own piece of mind. i put velcro on both sides of the BB for easy mounting of the nbox, and this way it keeps the new rca's nice, short and clean looking. too change battery sides, just unplug the rca's, flip the BB over and mount the nbox and plug in the rca's again. had to notch out the nbox for the cable leads. not a big deal for me, but maybe for others. its only a 25$$ box that can easly be changed out, but the 4 little notches r hardly noticable with the lid on and no leads coming out of the nbox. the new rca's were a custom job and a bit over kill, but happy with the end results. Happy building!!!!!! ed
