WRX Pinouts / Remote Turn-on

For the 2005 WRX factory 6-CD head-unit....

I am having trouble finding where to connect the remote turn-on for the amp I am installing. Obviously I don't want it powered when the car is off so I need something that is automatically switched with the ignition.... Furthermore, I prefer it to be off when the radio is off.... There is no accessory pinout that I can find like on most aftermarket radios. I was thinking of perhaps tapping into the ACC SWITCHED POWER (pinout #10) but then the amp would be on anytime the car is running, radio or not. How can I get it to power on only when the radio is on? Hoe have other people dealt with this remote turn-on issue? Will #14 UNUSED act as a remote switch like I understand it does on the Forester's radio factory?

Thanks. Mike

Hi

Actually what I ment was that, if you have "wakening power" coming from radio switch, I mean your radios switch that opens it, opens at the same time the amp, so you dont have the amp powered all the time either (only the radios on switch will give power to amp - not the background power mode). Im not an expert, but I had the connection made the same way in my former Audi. Sometimes it wasnt really nice, because the amp needs (at least that did) some time to "warm up" and it resultat that radio came on and the amp just after that (2-3 secs) with a power peek to speaker system.

I dont understand why you can not have the amp on, when the power is on in car (turning key turns the amp on)? The amp takes a marginal power when "idle" and it doesnt result any power leakage either, if you think that it will possinly drain your battery? This way you will also restrict the maybe not so harmful peek when radio is turned on and amp need warming up. For me this sounds the best way to do, but dont know as Im not an expert on HiFi.

Well yeah, but you don't wana power the amp through the radio. My concern is that whether the radio is on or not, there is always power going to it (right?) so powering the remote turn-on from the switched power could result in the amp being on whether the radio is or isn't on.

Does that sound logical or am I AFU?

Do you have a power aerial?

I've connected the remote wire to that wire.

Only thing with that is that you have to check whether the aerial stays up when you switch to cd mode, (mine does) some stereos pull down the aerial when you switch to cd, so your amp will turn off.
