[QUOTE="Litoffsnozzberry, post: 8775098, member: 684484"] so I ran all the tests. no voltage drop after the fuse, took it apart and retightened everything down. no breaks in the wire. i used a 12v power probe and ran the remote wire to the positive, still had voltage drop. do amps automatically recognize speaker impedance? alternator max output is 70amps alternator is 40-70 and the amplifier needs 501-750 watts which is 62.5 amps, if my math is right. didn't hook the amp up directly yet. if I hook up the amp directly and it still doesn't work what would that mean? if it does work but I can't measure any voltage drop on the main power wires could it be losing voltage at the head unit? had remote jumped and was putting 4-6 volts but couldn't find voltage drop on the main power plugs. was 14.40 before remote at amp even with everything unplugged. gunna check the terminals over tonight and get a DC amp clamp meter most likely. took a video of startup with probes connected dropped to 11.5 than right back up to 14.4 [/QUOTE]
