Title: Ignition live wire in boot?
Post by: wayneywoo on 18 July 2009, 23:59:41
Guys,

Is there anything in the boot that goes live with the ignition that I can tap in to for the amp remote turn on?

Thanks!
Wayne

NO !   >:(

Do not use anything else other that a correct remote turn on for the amp or you will damage the amplifier with a massive "turn on thump"

There is an electric aerial feed at the rear of the head unit, but under no circumstances connect the amp remote to an ignition supply.

OK Dave  :(

Amplified aerial......so this must be in the boot somewhere or can I grab it from under the dash somewhere or along either side of the car?  I really don't want to have to pull the head unit out again...

Do you know what colour(s) the wire is?  Plain blue or blue and white?

Not sure what the antenna feed actually powers, nor if the aerial booster in the rear is fed by this or ignition - need to check it with a meter. Personally, I would always take it from the rear of the head unit

Sorry, cannot help with location or colours - maybe an Omega owner can assist with that one

Dave, what would you look for when testing with a meter?

What's the difference between taking the power from Power Antenna / Remote turn-on / whatever vs normal switched live 12v.

Aren't all the sources 12v?

Is it sending a signal to the amp before powering it or powering it and then sending the signal......?

I`d be looking for a signal that goes positive 12 Volts when the stereo was switched on, and Zero volts when the stereo was switched off.

Power antenna signal sometimes only works when the antenna is required, ie: radio switched on, as opposed to a REMOTE signal that is on when the stereo itself is switched on. If you are listiening to the CD, then it is safe to assume that teh REMOTE would be ON but that the Power Antenna feed may not be required (common on many stereos)

Either signal has a short time delay on it so that the stereo is switched on at a different time to the amplifier thus avoiding damaging voltage spikes and signal "thumps".

Yes, but its the timing that is also critical. If you used an ignition feed, this would be turned on at the same time and would definately cause audio damage.

The correct wire is there, and if you use it, and wire it up correctly, then this question is redundant.
