make sure amp remote wire is connected to p.cont wire and not power ant wire on the radio
remote wire is to control amp, bass coming from subs, and the frequency
Yes a remote wire is necessary. You must wire the remote wire from the amp to and ignition source of power (a component which turns on when the ignition in the car is engaged.) i.e. the radio. The remote wire signals for the amp to power on.
Yes, the remote wire that hooks up to the stereo tells the amp to turn on, it works like a switch. If that is hooked up properly check your ground.
Either your remote wire from you head unit to your amp is broken or not connected properly, you don't have a remote wire, or your head unit is faulty. Try another piece of cable as your remote wire from your head unit, and if it still does not work, your head unit is faulty. To save buying a new HU, you could wire the remote wire to your accessories, but be cautious as you could flatten your battery quickly if wiring incorrectly.
You only need the remote wire if you have an external amp.
The problem you're having is an easy mistake. The wire you're connected to is not the remote wire for an amp. This wire you're connected to is used for a power radio antenna. That's why it's turning off the amp whenever you leave the radio.
Easy way to check were the problem is take a 6" piece of wire. Unhook the remote wire from your amp. Then hookup your 6" piece of wire to amp remote terminal then take other end and connect to the 12+ terminal. If amp powers up the its in the headunit. If amp does not powerup or goes into protect mode the amp is problem.
Why bypass amp just get wiring diagram and hook up remote"blue wire" to the remote lead from factory amp. Or unplug amp use a meter and check which wire has power. Then turn off radio and check wire again should have no power with radio off. This will only work if factory radio is still installed. But that wire would be remote wire. Just hook up new radio remote wire to the found wire. Then connect speakers to factory plugs and use the amp.
The remote amp turn on a 2012 Dodge Ram 1500 is the wire that taps on the harness to supply the 12v.
if your car has a factory amp you might have to mess around with the factory remote wire(this is what tells the amp to turn on) good luck
Amp always on
