I own a older Buick and wanted to upgrade the alternator. How large of an alternator should I upgrade to?

My Buick is a 1985, what is a safe amperage of alternator should I upgrade to? And yes I am running a stereo system. A 1500 watt Autotek MM and four twelves.|||205 amp single wire GM alt|||Got your alternator right here Buddy!!!





oh, and add a second battery, use an isolator and throw it in the trunk. Much better performance than a bunch of capacitors in your system.

It should also last longer|||a 180 to a 200 amp one wire gm alternator should be plenty for it,that will also supply enough to run the air and anything else that the car needs,good luck on it.|||Run a 190 amperage alternator. If you want, run 2 batteries and an isolator so the main battery won't be dead and your stereo is running off the secondary batter.|||as big of one that will fit the brackets.... it will only supply what the system calls for.. look for one from a cadilac limo or a gm based ambulance etc..|||Take your alternator to a alternator shop that rebuilds them and ask the rebuilder what he thinks you need, I have had them rebuilt from an 80amp to a 125amp. The 125amp should work fine for you unless your amp has already drained your battery once and you have fried your alternator a few times already. You may need a bigger battery and alternator, or less amp.
