I would like to install a stereo in my 2006 Kawasaki Mule

anyone who has experience in this I would be grateful for help on wiring I know I gotta find a switched pwr supply but I really don't wanna take a chance on picking the wrong one.

A meter would help you find the right wires.

try using marine audio products they will hold up better in that i would bet

sold the mule now I have a 07 Yamaha Rhino.

I have all Kicker Marine components but I will be running a Pioneer DEH P8600MP for head unit. Has anyone had any experience w/ this install?

which wire behind the ignition is the best for a switched 12+?

accessory, if applicable is ideal over ignition. get a digital multi meter. the acc wire will go to 12v and drop to 0 during crank and then back to 12v while running. ignition, will go to 12v, and stay at 12v thoughout crank and while running.
