    So I got my car back 2 days ago and for some odd reason the radio will not turn on. I checked all the fuses and wires and everything seems fine.
    I've held down the power button multiple times and tried resetting it... still nothing.

    My headunit is a Boss Audio 642CA (http://www.onlinecarstereo.com/CarAudio/p_28588_Boss_Audio_642CA.aspx).

    Now on to the catch...

    Recently my battery has been dying if I let the car sit for 2-3 days without turning it on. I just came to realize that when I turn the car off, the headunit turns on (I hear it looking for the CD inside). It does this continually. I'm assuming that this is what's draining my battery.

    Why is it that the radio is on (I assume) when the car is off and vise-versa.? Any ideas?

    did you check the two fuses you thought the manual directed you to or did you check them all? If you have not pulled and checked every fuse we need to start there. I know it sounds like a hastle but trust me that it will take less time to physically inspect every fuse then to go through the manual. Don't forget the box by the battery.

    Once we are sure that every fuse in the car is good then you will need to dig out a volt meter or test light to verify that there is voltage on the power wires behind the deck.

    Will do. And no I did not check those wires. They radio worked fine up until recently, never had a problem like this.
    Any idea of the radio follows a wire to the map lights? I know they share the same fuse and just recently I unhooked my footwell lights that were soldered together.

    Which 2 fuses are you talking about?

    I've checked the 1 fuse on the back of the headunit, all the fuses under the steering wheel, and all the ones in the engine fuse box.

    There are two power wires for the radio that are fused, the ignition and the constant. I don't know which two they are because I have not read the manual for fuses since I got the car again because it takes longer. If you have pulled and inspected all the stock fuses then get your volt meter or test light(or borrow one) and check the red/yellow wires on the deck to ensure with the key on you have 12v on it. Again though if you have not literally inspected EVERY fuse we need to start simple and do that.

    Well the radio has power while the car is off. That could mean one wire is hooked to a constant power so while the car is off, there's power. Double check the wiring, its possible they moved some wiring while doing the swap.

    I noticed this yellow wire leading to the pigtail seems to be pretty loose. That wire is Memory 12V+.

    it looks to be wired correctly. A loose wire in the hrns would cause it to not work, or work intermittently but it would not make it turn on with the key off. If you have a volt meter or test light stab the red/yellow/black wires with it with the key on to confirm that there is power on the red/yellow with the key on, and that the ground/black wire is a good ground.

    Will do, I don't have a voltmeter but I'll cruise over to my buddies this week so he can check it out. Thanks Scott.

    you can get a test light for <$10 at an auto parts store. Great addition to a tool box if yer buddy is busy.

    Definitely invest in a multimeter, one of the best tools you can own.

    Ok so I just picked up a multimeter and the red wire (12V plus) and yellow wire (Memory 12V) are fine. Both are reading at like 12.06 or so. The blue wire (power antenna) reads 0. I'm pretty sure that that wire isn't the reason it's not turning on though. Maybe the headunit is just on its way out.
