    Hardwire? Audigy 2nx?

    I wish to run my audigy 2nx off he 5 volt lead on my opus 150. I picked up a radio shack adpater plug to hook into the audigy so I don't have to cut the original adapter. 2 questions
    1) When i'm hooking up the power to my opus, shoudl I put an inline fuse?
    2)On the radio shakc adapter plug there are two prongs. Does it matter which prong do I hook to positive? There are no markings of any sort that would clarify if either is positive.

    Thanks for any input.

    This is exactly how I wired up mine... I did not use an inline fuse, I figured the OPUS itself already has an inline fuse to it and there aren't inline fuses to each of the hard drives you hook up to the Molex wires, didn't see the need...

    I bought the little white replacement plug from Radio Shack as well, the one that you can plug the end in one way for (-) inside (+) outside or vice versa... But I do not for the life of me remember how I determined which way I wired it. It is tucked pretty deep in my glove compartment area. I have to take my opus out this weekend to disable the constant +5 on it, I will look closer for you while it is accessible to get you a better answer. All I know is whatever I chose was correct way to do it, everything works great...

    near the plug on the back there should be a little diagram indicating the polarity it kinda looks like (+)-C-(-), and theres a dot inside the C, in this case the middle part is negative and the outer part is positive. Alternatively you could just plug in the original power supply and measure it with a multimeter.

    Hi ML430, I'm looking to put in a 7" Lilliput screen in my '02 ML320.

    Do you have any tips or posts on how one might replace the main radio with an entire setup? I have the non-NAV radio, but it still comes with a LCD unit.

    TIA,
