If your car head unit has no remote wire, when you switch on your car head unit, the amplifier will not switch on because the remote wire can't send voltage to the amplifier to make it come on, but you can still get around it.
1)To power on a car amplifier without using a the remote wire connection found on the wiring harness on the radio, simply cut a small piece of 15 gauge wire and using a wire stripper strip of a 1 cm of insulation off both ends of the wire.
2)Once you have removed the insulation off both ends of the wire, unscrew the 12 volt terminal screw that's on the amp, you will require a screwdriver to open the screw.
3)Once you have unscrewed that screw, unscrew the remote wire terminal screw.
4)Then insert the electrical wire into the 12 volt terminal and using your screwdriver, screw tight the screw.
5)Then insert the remote wire into the remote wire terminal and then tighten the screw.
You have now bypassed the remote wire, now your car amplifier will power on without a remote wire connection on your car stereo. The only downfall of using this method to power your car amp is that it will be on all the time, it won't turn off. So when you are not using your car amp, disconnect the fuse, it will break the circuit and turn off the amp, if you don't, the next morning your car battery will be flat.
Now that is a totally useless solution to a legitimate question...shouldn't you run the power from a source that is only energized when the car is on?
ReplyDeleteThe another solution would be getting another connection from acc and this way it will only be on when when you the car in running or on acc. hope this helps :)
ReplyDeletesimplest thing ever: do as said above, but add a switch to that piece of wire. Don't forget to turn off the switch when you get out of your car.
ReplyDeleteConnect it to the back of ciggarette lighter
ReplyDeleteJust find the wiring diagram for your factory unit on the web,and splice in to the acc wire. Your amp will then go on/off with radio.
