i just called EVERYWHERE in this lovely state(wisconsin) i can think of to find a HO alt for my car...(97 mazda protege LX) and they all told me the same thing....half of the work for the alternator is done by the brain box which i guess is tied in with it...its like the voltage regulator and everything, it is even tied in with the fuel flow management...now this is bogus...im stuck with a puny 70-75 amp alternator and there is nothing i can do about it :( now i have to see if i can even get away with running 2 optima batteries in there with that alt. on my voltage gauge i put in with the system, the car idles at 14.7v and when driving its at 15.1v which i guess is awsome but i still need the extra boost....what do you guys think? think im screwed on this part? lol

Well, I guess it depends on your plans. Have you tried Mazda directly to see if they make a "heavy duty" alternator (with all the necessary electronics) for your car? It'd be a lot of money, probably, if they do make one. With a 75 amp alt, you should be able to support 300 or so watts of amplifier power without any problem, so you could go for high-efficiency speakers and get decent SPL. Or, again depending on how much you want to spend, you could have a bracket fabricated and run a second alternator dedicated to your stereo system. Check with auto electrical or higher-end car stereo shops in your area, or contact Zena and get a quote.

I applaud you for thinking of this and planning your power system. Far too many people leave this to last and then wonder why their "awesome" system sounds wimpy and kills their battery and sometimes the entire car's electrical system too...

Thats bull, an alternator is an alternator. What ever follows after that is just that. Nothing can actually be attached to the alternator to control your car other than the regulator.

Have you called specialy companys such as www.mechman.com , www.mean-green.com , ohio generator?

Go get a junkyard alt and have it rebuilt. It shouldn't be a much a problem doing it this way.

Dommonick is one of the best alternator builders in the world! I would put my name against that. He just recently started selling on ebay. He is a large supporter and competitor in the Usaci and DB drag curcuits

Just see about getting it- or another one- rewound.

15volts while driving is pretty darn good IMO..

I need quality equipment, feel free to donate.

Not exactly sure what you're trying to say, but I can say that computer controlled alternators have been in use since at least the mid 80's with Chrysler.. I can state that GM is currently using the ECM to control the alternator (I can hook a scan tool to a GM car and turn the alternator on and off), and a quick google search shows that Mazda is indeed using the car's computer to control the alternator.
