ok so i know you can get a saab altenrator to fit on the mercedes .. but my question is will it hurt anything if i put a 120 amp alt on my car ? what if i even went up to a 150 amp alt ? reason is my car stereo pulls allot of juice and i need the extra for it .. but im afraid of frying something .. i dont always have the stereo blasting away so would all the extra amps be harmful ?

my car is a 300 se 1988 3.0L

It's a popular upgrade to install the higher amperage alternator from a V-8 S-Class into the W201 when the bass beat of the stereo starts to strobe the headlights.

The alternator will only create enough amperage to handle the load.

What you will want to do is repalce the flimsy stock wiring to the alt with some 0 gauge wire. That's all I did whenI swapped out the 65amp alt for the 115amp one on the 300SD.

wondering if you ever upgraded and what you upgraded too. V8 S class isn't specific enough for me to go out and purchase any random alternator.
