I’m building a metal roof for a 15 rzr 900 4, going to have a Jvc Bluetooth reciever and 2 switches on each side for the front area along w 2 6×9 and 2 6×9 in rear, done lights and front and rear LEDs. Now if I use blue sea fuse block, could I install fuse block in roof and only have one positive and groundran down from roof? Would like to have them ran in roll bar.
