A:Answer The power supply is just a positive and negative wires with a 30 amp fuse. What I did was striped a battery tender wire, the set I bought came with the bolt on ones that bolt to the battery and the clip ends like jumper cables, so the bolt on part I put on my battery and cut the jump cables end and used the male and female end to wire to the power wires for the amp so now all I gotta do to turn it on is hook those two pieces together. It’s not hard to do at all.
