How to wire an amp without a remote wire ?

To wire an amplifier without a remote wire, you can often use a method called “signal sensing.” Some amplifiers have a feature where they can automatically turn on when they detect a signal from the speaker wires or RCA inputs. Alternatively, you can manually connect a switch to the amplifier’s remote terminal to turn it on and off.

A remote wire is typically necessary to properly control the amplifier’s on/off state. Without it, the amplifier may not power on or off correctly, leading to issues with functionality and performance.

Using speaker wire as a substitute for amp remote wire is not recommended. Speaker wire is designed to carry audio signals, whereas a remote wire carries a low current signal to trigger the amplifier’s on/off state. Using speaker wire could potentially cause electrical interference or damage to the amplifier.

Yes, you can run an amplifier without RCA inputs by using speaker-level inputs if your amplifier supports them. Speaker-level inputs allow you to connect the amplifier directly to the speaker outputs of your car stereo or other audio source.

To wire a remote wire for an amplifier, you typically connect one end of the remote wire to the remote terminal on the amplifier and the other end to the remote output of your head unit or a dedicated remote turn-on lead from your vehicle’s fuse box. This allows the head unit to send a signal to the amplifier to turn it on or off when the vehicle’s audio system is powered on or off.
