HELP! Wiring issues on Boss PV3700 amp and I'm too ignorant to figure it out

[Rowdyrod59]

Installing a Boss PV3700 amp in my son's Durango. Ran all the wires like manual said, but the amp won't power up. Put my multimeter on the power and ground (key off - 0.00v), (key on - 0.00v); Ran a wire from battery ground to connect to my multimeter and rechecked (key off - 14.7v), (Key on - 14.7v). Checked the ground output from the amp to the car (neg multimeter cable connected to neg battery terminal, positive cable to amp ground - 14.7v with key on or off). Remote switch source (key off or on - 0.57v). I thought that maybe the problem so I made a jumper to supply 12v source. Still nothing. I don't know much about electrical and I don't know where to go from here. Any help is greatly appreciated.

You have a bad ground connection. Remove all the paint from the body at the ground point and try again.

Thanks for the response! I'll run a separate ground wire in the morning and see what happens. I'll post the results.

Thanks for the input. I ran a better ground wire and it works great. I appreciate the help.
