:thumbup: aka remote to power your amp...lesl2 said:You should use the control signal from the radio. This will turn the amp on only when the radio is on. This is pin 16 from the radio. If you have an amplifier in the trunk, this is the white wire to the amp. If not, then you can get it off the white wire on the antenna amplifier. This is only the control wire. I assume that you know to pull the positive voltage straight from the battery.
