Help! Wiring the Alpine KCA-SC100 to the Alpine CDA-9885

[jweible]

So im definitely a newb to car audio. Im more home theater prone than anything. So, to get down to business, I have the alpine CDA-9885 which is satellite radio ready. I want to receive sirius satellite radio service through my head unit. So I went out and purchased the Sirius SC-C1 and the Alpine KCA-SC100 which enables the tuner to be plugged directly into the Alpine head unit via the Ai net interface. Now my problem is (and this is where my car audio skills go to crap) powering the KCA-SC100. Meaning I dont understand how im supposed to ground it, as well as hook it to my battery. I have a Honda Accord EX 1993 model. Any info or help would be greatly appreciated. Thanks for reading guys.

To ground it, you'll have to find a good spot on the body of the car. The negative battery terminal is connected to it, making it a large distribution block. Find a spot (kickpanel perhaps) sand it down to bare metal, then crimp a ring terminal on the end of the wire and use a self tapping screw to hold it there.

Youll have to specify whether the + on it goes to the batt or to the ignition of the car.

Where are you putting the unit?

If it's close at all to the h/u just use the headunit's power & ground. Should be fine.

If not, you can ground a different location as suggested above, but I still think you might as well just run some wires to the h/u's power & ground and call it a day.

When you say head unit's power do you mean connecting the yellow wire from the harness connected from the KCA-SC100 to the yellow wire on the head unit's harness??

I love you guys. So this should be pretty easy then right? I mean for a first time car audio install? Any tips or anything I should know before taking the big plunge?

Nope its not that hard, as long as your not color blind. //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

I don't know that particular Sirius unit, so I can't say for certain that the yellow wire of the unit is a constant power (yellow wire) or switched power (red wire). I would think it's a switched power.

Check the manual to find out. It should say specifically. However, with standard industry uses for yellow being constant, it may indeed be a constant power wire.
