i just replaced my alternator.. n then realised.. its 55 amps... the stock 1 was 65 amps... does tht effect ? everythings running fine...

 

Won't make a difference unless you like running your A/C on high and turning up ur stereo all the way up... While simultaneously having your healights on and everything else in your car that takes up power turned al the way up, plus having a stick jammed into the alternator.
