[QUOTE="retrojordans, post: 7266735, member: 630134"] Lol you throw around this word "upgrade" what are you talking about...A high output alternator for a 1000 watt amp WRONG! ....Tons of people run 1000 watt rms amps on completely stock systems with absolutely no issues and that includes compact cars with 70 amp alts....If a 1000 watt amp requires "75 amps" as you claim those car's -- with 70 amp alternators -- systems would be running almost completely on battery power...And that just isn't the case you are just flat out wrong. 1000 x 2 to incorporate an inherent amp efficiency of 50% (which is overcompensating) = 2000 / 13.8v (average alternator output voltage) = 144 / 3 because music will not be constantly drawing 1000 watts like a burp or test tone = 48....And that's with a hypathetical 50% effieciency...some amps run @ 90%... He won't need to upgrade a **** thing with that amp on any ohm load.. [/QUOTE]
