I need a new alternator and I was looking at AutoZones website and they list a U.S. one at 90 amps and a Canadian one at 110 amps. What's the deal with that? I would think they would all be the same. I have a sub and at night with the lights on and the music going while sitting at a light, you can see the Battery gauge needle dipping with the music and the gauge lights dimming. So.....I was thinking if they mounted up the same and it wouldn't hurt anything, I would splurge the extra 10 bucks for the Canadian model. Would this work or cause any problems?
