well it did in the manual say you could use antenna but it says

DO NOT connect this wire to a negative position or to any device that requires high current

I am assuming an amp is a device that requires high current???

edit: its a custom autosound usa-6

it is built for classic cars

antenna, must be an old radio, old ones only had an ant wire

no the antenna is always up and im pretty sure the wire always gets power when the radio is powered on

im afraid if i try hooking up the remote wire to the antenna wire it might fry my head unit

If you are desperate you could always wire it up to the fuseblock in a space that is off when the car is off and hot when the car is on.

Ok then use antenna, lol...

Use a DMM to see if the antenna wire fires 12v when turned on?

just connect it to the accessory wire. from your diagram that would be the red one.

oh and antenna usually only puts out power when the radio is on. not with cd or other source. so you would not want to use that

that wire is to tell the ant to go up when the radio is on, or your amp

on old radios the antenna will not move up and down. hook to the antenna wire.
