Remote Amp Turn -> PITA Posted by SLAAB [Email] ![]() ![]() In Reply to: Re: problem with remote wire for amplifier, Jeremy R., Tue, 10 Dec 2002 18:23:07 Members do not see ads below this line. - Help Keep This Site Online - Signup |
OK. Here's the saga of my remote turn on solution:
I tried using the antenna wiring, but only found the constant power, and the other wire was negative only.
The pre-amp turnon lead from the head unit was only 4 Volts.
The antenna turn on signal from the head unit did not have enough current to turn on the antenna and amps.
Wiring the turn on into an ignition switched source created thump.
Wiring the turn on into one of the speaker leads resulted in the stereo being loud or very loud.
Eventually I tried the bright idea of using a relay with the antenna lead as the trigger and the power from an ignition switched source. Basically the electromagnet in the relay drew too much power from the antenna lead that the antenna didn't work and still no turn on.
Then I tried the relay trick using the factory preamp turn on as the trigger. 4V does not do the trick.
What solved it? A little device from Peripheral Components called a Low Voltage Trigger. Used the 4V preamp turnon from the headunit to trigger an ignition switched 12V source. Worked like a charm. Soldered the mutha in.
