How can I get the power outlet in the cargo storage area in my Jeep to turn on and off with the ignition? I have my subwoofer plugged into it runs the battery down because it just stays on all the time.
One, the power outlet isn't meant to run anything over about 100W so your subwoofer amp might be straining the wiring on it.
Two, your subwoofer amp should turn off and shut down with the head unit.
Three, the power outlet should already be turned on and off with the ignition. Every one I have seen has been.
If the amp is running your battery down, there's something wrong with it.
Actually, the way I have this sub wired is strange. It's a subwoofer for a normal home theater system. I have it plugged into the poweroutlet through a 400W DC-AC inverter so I can't hook that up the headunits ignition cable.
That's a waste of money I don't have... This works great! I just need it to turn off with my ignition.
You picked the one power outlet that's always on LOL ...
Well in short, you're outta luck ... you can rig a switch (simple on/off) to the power outlet and run that wire all the way to the front of your vehicle and mount the switch somewhere, and always remember to flick it off ... or if you get a cheap amp and subwoofer combo off craigslist, it'll have a remote turn on, that'll automatically turn the amp and subwoofer on and off ... if you get it off craigslist it shouldn't be too much

Another way would be to run a tap wire off something you know switches with the ignition (cig lighter?) to a relay in the back. Have that wire activate the relay. Have the relay drive the power coming from the power outlet, through the switched contacts of the relay, then out to the inverter. Voile'. Inverter turns on and off with the ignition.
i would bypass the power outlet altogether, run some beefy wires out to the back from the battery, and switch it with a relay and switch on the dash or link it to an ignition circuit. then you could put a fused distribution block in the back and hardwire your inverter back there. that way you would not have to strain those tiny wires risking fire, and also have a power source ready if you decide to install anything else back there. save the power outlet for charging your phone. thats what i did.
