Turning on the amps/radio without keys?

[Afboy143]

The reason I am asking this is because I am showing my car off next weekend in a show and I want to keep my amps/radio/gauges on but dont want to leave my keys in the car to have it all on. Is there anyway to make it all on as if the key were turned back without leaving my keys in the car?

also wind your red and yellow wires on the back of the deck together and hook them to constant 12 volt power.

just remember to turn it off when not in use

Um, maybe my ignition switch is worn, but I can turn my key backward and then remove it with the radio still on.

yea i think yours is sberkel, I just went out and tried, radio comes on when key is backwards obviously, but my key won't come out

yeah just put power directly from the battery (use 12 volt tap or just wire straight from battery) to your remote wire. But hope you don't leave the car off to long, play that system loud enough and you'll drain your battery quick!!!
