Switchable power in Trunk

[torresmd]

I am installing an amp and aftermarket subwoofer enclosure. I have 2004 bose with nav and sure would like to locate a switchable power lead in the trunk so that I don't have to go into the dash or through the firewall.

Is there such a thing?

Thanks,

Steve

I searched high and low for this through many schematics. Unfortunately I didn't find anything in the trunk but my amp was able to switch on/off with just the 12V and GND attached. I ran the 12V from the Battery terminal and ran the ground from an existing ground post in the trunk. I had no idea it would work that way and actually discovered it by "accident" while I was trying to find a switched power lead. The amplifier is a Kenwood 9104D - a fairly recent model so your amp may be able to do the same thing?

I think this was covered on the 996 Carrera forum a short while ago. I recall that the conclusion was that the heated washer nozzles are about the only ignition-switched supply up front.
