[QUOTE="bumpasauras, post: 8310141, member: 607820"] As a general rule of thumb you want to add up the fuse rating of all the amps you are wanting to power. Shoot for an alt that has an amp rating as close to the sum of your fuse rating as you can afford/fit. Say if yor sub amp has a 100 amp rating and your mid/high amp has a 40 amp rating then you will be shooting for a 140 amp alt. For every 10-15 amps below the 140 amp mark add a battery.. This is a crude rule of thumb but it will get you in the ball park.. I build alts on the side so lemme know what type of vehicle and what equipment you are trying to power and I can tell you what amp rating you will need and about how much you can expect to pay. Just to be clear anything above your fuse rating is great.. I usually advise my customers to buy the largest alt possible (within reason) to allow for future upgrades [/QUOTE]
