Need help installing new stereo

I just bought my girlfriend an after market radio for her car ('05 Cobalt) and i tried to install it but i couldn't figure out how to hook up the red ignition wire??? Anyone here have any experience with that?

I've installed lots of stereos myself before but i never came acrss a wire harness that did not have ALL the wires within the clip, that is where i drew a blank...i just have no idea where to hook up that cable...any help would be GREATLY APPRECIATED

you're gonna have to tap into a constant power source for that. most people buy an item called add a circuit. it hooks into a fuse slot in the fuse box and has a wire attached so you can basically add a circuit. most use the windshield wiper fuse

So i just choose any empty slot in the fuse box and insert it in there? I actually saw one of those at a n auto zone today and i talked to a guy there and he told me that it wouldn't work. When i first saw it i thought it was perfect but then he busted my bubble...

no, you take out an existing fuse, and place it there. it comes with two fuse slots, one for the existing fuse, and one for the new circuit. it will work because i've done it myself.

you can use the wiper fuse location, you can find it the the amp DIY i made

Make sure you are hooking up the right power wire, there will be a 12v constant and a 12v ignition, the constant is for memory settings and the ignition is where the stereo can only be turned on with the ignition on.

yeah, the one i needed help with is the red 12 vold ignition cable, not the constant one (that one is yellow)

yeah, use the wiper fuse i mentioned, it is only active when the car is on

Thanks so much I really appreciate all the help. You guys are awesome! :D

no problem
