[QUOTE="Jepalan, post: 8171680, member: 655519"] You guys have the concept *generally* correct, but your terminology is a little off. Don't confuse *voltage* with *power* (watts). If the amplifier was perfect then it could put convert all the *power* available from the alternator into *power* into the speaker. Under this simple assumption if you are putting 2400 Watts of power into the speaker, then you are pulling at least 2400 Watts from the alternator. Since the charging system runs at 12 volts (approximately), your alternator needs to be able to produce 2400w/12v = 200amps (rms) You will need a high output alternator to produce 200 amps rms at 12v [/QUOTE]
