High Output Alternator for euro spec BMW????

 

BMW installer
Unregistered guest
Hello All,
I have a euro spec '89 BMW 525i M20 E34. I am trying to install a stereo for competition purposes and have not been able to find an alternator suitable to run it. Currently I have the stock 80A alternator. I will be running a few Soundstream 10.0's, the old ones, and a Picasso. The potential ampereage draw is around 160A. Is there anyone who knows where I can buy a factory replacement or maybe a custom made alternator for this application? Surely someone has built a power-hungry stereo in a BMW. Thanks.

You might even see if you can find an auto salvage yard around town that specializes in BMW's or German Cars... that's what I did and it only cost me $70.

http://www.hoalternators.com/ did a custom high output alternator unit for my 760Li rated at 200A. Bolt-in plug-in with no mods to my car. Very expensive tho.

Find a used alternator for your 89 BMW and send that in for upgrade to 4alterstart.com. They can turn it into 175A - 200A. When you get it back, all you have to do is just replace your stock model.
