[QUOTE="joshpoints, post: 298154, member: 546465"] I'm not an electrical engineer and don't know that much, but out of all honesty that quote doesn't make sense to me. A system that is rated at 3000watts rms when played loud is going to draw 300 watts. Now just because an amp isn't totally efficient doesn't mean that it doesn't draw the electricity, it just means that an amp wastes some of the electricity due to resistance and so on. The wasted power is turned into heat. Something that must be realized is just like audio equipment some alternators are overrated. Some of them may say that they produce 105 amps, but realistically they produce no where near this amount during typical driving. Some companies may rate an alternator at 105 amps, yet the alternator only produces this peak amperage at 5-6k rpm. This means in everyday driving you are getting no where near 105 amps. THis could be part of your problem. Before buying an after market alternator find out at what rpm this rating was found at. IT's just like that amp thing. A company builds a trashy amp that is able to peak at 1000 watts for a second, but can't produce a respectable rms wattage. If this was already stated sorry, but I was too lazy to read through the other posts. [/QUOTE]
