Absolutely.a 4kw amp will do just fine on a 250 Mechman alt and 2 D3100's.i do agree with this. i ran a 200 amp alt. with big 3 a regular bat under the hood, 2 HC2400s in the rear supporting a memphis 4000 and i didnt see under 13 volts.At a stop light I drop to 700 rpm. Sure I could sit there and rev it to 1500 to get huge output...but why? The 250 amp is a much better daily application. If for competition, sure just hold it at 1500rpm and get 330 amps from the big alt.</blockquote>
