12volt power source from Mach 500 Stereo

[COBESGT]

Does anyone know if the factory MACH 500 stereo puts out a minimum 5 volt signal to turn-on/off some other device? I've checked everything that I can in the car at the back of the radio and I can only find one that sends out 4 volts (aux output). I'm trying to get my powered sub to turn on/off with the radio and I need a 5 volt source. I can use the accessories 12 volt source, but that means my sub will turn-on whenever the key switch is on, even if the radio is off.

Is there another location in the car where the radio switched 12volt power is located?

Any ideas or experience with this same issue?

i assume you mean "shaker 500".. at any rate the factory amps on this system require 5v. i actually swapped my head unit out to an aftermarket and had to wire in a 5v voltage regulator in order to keep the factory amps for the front subs. with that said you could prolly just tap into that source for your amp

Wow, I feel really stupid now! Yes, it's a SHAKER 500 system. I tried the AUX wire from the radio and it only had 4.6 volts, which wasn't enough to turn-on the amp for my sub. perhaps it's because the battery is at less than 12 volts, from sitting all winter long. I'll charge the battery and try it again. Thanks

There is a fuse in the passenger side kick panel labeled something like "Delay Accessory" that I tapped off for the remote lead on the amp. It gives the delay the radio gets when you turn the key off.
