6 Disc Changer
 

Ok, I have already posted a thread asking about installing a Clarion 6 Disc Changer to a Pioneer head unit. I found out that it is possible, but I have to install it with an FM modulator. This means that once I get it installed, I will have to run the changer through an unused frequency on my radio. The problem is that to hook up the modulator, I have to wire it in to both an AC and DC power source, and a ground. Well, I know that the DC power source would be my battery, and I obviously know how to ground it. But, where do I find an AC power source!?!?! :wallbash: One of my friends told me that it might have something to do with the fusebox, but idk if I believe them. Someone please help! :helpsmili

Ok, after talking with some friends, I think I might have figured it out. It says on the instructions a non-continuous power source. One of my friends told me that I could just hook it up to my accessory wire. I think I remember reading something about that on the internet too. Sound right to anyone?
Also, how do you know if you have too much of a load on your battery? I know that you can only run so many things off of your battery without getting another one, but how much is too much. Isn't there a way to measure the load on it and tell if its too much? Currently, I have hooked up my fog lights, two red interior lights, and will soon be hooking up the 6 disc changer and some subwoofers....would this be too much?
