Alternator
 

Yea... I have the stock, 75 amp alternator inmy car. i they put a 1000w amp in my car for subs.... alternator blew out... then i got a new 130amp alternator... i was puttin it in today, and the bracket it rests on wont let me screw both screws... if i screw the bottom on, it feels sturdy.. but i dont know if i can puton the belt with one screw... so if i return it for the 75 amp alternator, and run a capacitor for my subs.. will the not ruin the amp.... or cani leave in the alternator with one bolt.... or can i change the mounting bracket that it rests on... please help me lolol

You need to cut away the webb on the bracket so you can get the top bolt through on the alternator. Get a high speed drill and a metal file/cutting bit.
