Need to turn the key twice to start the AMP

[PatrockNL]

Hello,

Recently i installed my first subwoofer in my car. and it works pretty good. except that if i want to turn it on, i first have to start the headunit, this first boot will send my amp into error mode. when i remove the key from the car the headunit and amp turn off. when i start the car after this the headunit and amplifier power up normally and the bass starts kicking.

All the wires are connected properly. what could be the origin of this problem? is my battery to weak?

I always stop the CD or my ipod when I turn my car off, then it doesn't immediately try to start playing when I am starting my car.

the headunit is still in the proces of turning on. as soon as it gets power, the amp turns on via the signal, and inmedietly in an error mode. if i promptly remove the key from the ignition and turn the power of, and turn the key to the on position again. it starts up normally and everything works.

I'd try and put a switch between your head unit and amp. Have it off when you start your car, and flip it on later. See if problem persists.
