Hooked up to the alternator?

Hey...

This guy is telling me that his buddy hooked up his amp to his alternator...does this make sense, or is it even possible? I've never heard of hooking a system up to just your alternator...I thought it had to be from the battery...I mean the alt. generates current which charges the battery, and the battery has voltage...??? Tell me this guy is full of sh_t please //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

tmk theres no difference- the pos lead off the alt goes straight to the batt....no difference....everythings wired in a parallel...

That's how I did it on mine too. Put a lug on the 8 gage wire and screwed it to the allternator's output stud.

How does it work though without the car running? Also why would you hook it up like this? What are the benefits and drawbacks...

Thanks for the replies...

It works when not running because there's also a wire going from alternator to battery. So they're connected anyway. I just put my amp power wire at the alternator end of the wire instead of the battery end. With 8 gage wire and 300 watts it's no difference.

I chose to do this because I have a side terminal battery and the terminals are a pita to deal with. Using the alternator output stud was simply one #10 ring terminal and it's done. Simple.
