Alternators are an often-overlooked component of an engine build—that is, until you install a big stereo or spin your motor north of 6,000 rpm.

For instance, it’s got a new 400 amp alternator well suited to the demands of power-hungry audio/subwoofer amplifiers.

Even better, Mechman says these alternators can spin up past 6,000 rpm with no trouble.
