Hey I just wired my car and instead of hooking the power supply to the battery I hooked it up to the altenator. What are the pros and cons to this?

Will this still create 12 volts for my amp or will it be more or less?

Yes this will work, most if not all alternators have voltage regulators built into them, however a battery tends to smooth out "ripples" in the supply path. Usually it's a better idea to hook up to the battery or dedicated power terminal, rather than the alternator.

Top Secret, I can tell you but then my wife will kill me.

ya, you will even hear the ripples, not a good idea. Very bad for caps that need to be regulated. Not to mention that if you suck too much power, your amp will probly turn off casue theres no reserve (a.k.a: battery)

So you guys are saying I would be better off taking my power wire off the altenator and putting it on the battery. Or do u think I should try it on the altenator first?

well you have a choice flash......you could either hook it up to the alternator and get equal results PLUS ripples....OR you can just hook it up to the traditional battery and not have to worry about ripples......remember my friend, in a mobile electronic installation you want to lessen ripples as much as you can.
