    Im hookin up the XM radio i got for my blazer, Can I just splice into the 12 volt source and ground for my CD player? Then I can have it set up to only one when the Key is on ya know.

    It came with another cigerette type connecter to plug the 12 volt to 5 volt adapter into, so im not going to have an issue there.

    I could use one of my 3 other cig type deals but im trying to keep it lookin clean. Thanks guys

    You should be able to.
    Couple of things to watch out for though.

    1) Unscrew the top of the XM radio's power cord cig lighter and see what size fuse is in there, and make sure the circuit you tap into doesn't exceed those, or buy yourself an inline fuse of the same amperage to put on your hard line.

    2) make sure there is no special power requirements. Some devices (like my GPS) have a little PCB board inside the cig lighter which converts the power to whatever. So, in order to tell if this is your case, again, take apart the cig lighter that came with the XM radio and ensure it's just a fuse and nothing else. You can also check by cutting that line and hooking a meter up to the bare ends coming out of the cig lighter and ensure it's just plain 'ole 12v.

    I was told that the cig lighter droped the voltage down slightly somehow and the plug for these toys works with that voltage not 12v. Could you buy another cig lighter and mount it behind the dash or in the dash?

    Some do, some don't, my Sirius plug&play radio does not, my GPS does. If you take apart the cig lighter and/or measure with a meter what's going into the reciever plug, you should be able to tell.

    they sell a cigarete plug with a pigtail at radio shack that works great for this. I used one with my XM radio so I could hide all the wires behind the dash.

    yeah my Express XM kit came with a cig plug with a pigtail on the end, thats what im going to splice into with.

    the cig deal is an adapter to go from 12 to 5 volts, so i cant simply bypass it.

    I plan on burying it all inside the dash for a clean look
