Will changing my car altenator to a higher amperage alternator damage my cars electronics?

I%26#039;m planning to do a big three, change to a higher amperage alternator and changing a higher amperage battery, will that damage my car electrical component?|||The voltage is the important thing. The alternator can be a million amp capacity, but it will only put out as much as the system needs.|||no your alternator only charges your battery the amps that come out of your battery will be the same...and i doubt your it will hurt anything having a higher amp as long as there are fuses hooked up to everything|||no,but you might have to change the alternater fuse if your car has one. I did a similar change when I had a car that had 5000 watt stereo system and had no problems|||nope all is good
