What To Do If Your Car Head Unit Has No Remote Wire

What should i do if my car head unit doesn't have a remote wire wire?

If your car head unit does not have a connection that connects to a remote wire, then you are left with two choices. If there is no remote wire, your car stereo can't power on the car amplifier. The first choice would be to buy a car head unit with a remote wire connection and ditch the car head unit that has no connection to connect the remote wire.

The second choice would be to connect the remote wire, with a wire that provides a 12 volts source. You can use, for example a cigarette light socket as a 12 volts source or your car's ignition. But the only downfall of connecting the remote connection to a 12 volts source can be, your car amplifier might go into protection mode, especially if your have a Alpine car audio amp. If you want more control on when you want your car amplifier to turn on and off, using this method, simply run a switch between the 12 volts source and the remote connection on the car amp.
