I've a car audio system installed in my bmw 320i (2000 model year (E46)), very powerful (about 2000W) but It require a lot of energy to feed it. So I've installed 3 batteries system that provide about 2700 Amp, but the problem is how recharge it? The OEM Alternator provide only 120A and i need at least 200A !!!

But I can't find an adequate alternator to fit...

can anyone help me?

thanx in adavance

greetings from Italy

A 120 amp alternater is more than enough power for 2000 watts. Unless you listen to your system at high volume constantly while driving. If you listen to your system with your car off then extra batteries are helpful. Otherwise they just will increase vehicle weight. Try adding extra woofers.
