These alternators are the highest rated alternators today's technology can manufacture and are designed for competitors wishing to improve their maximum SPL. Only recommended for serious installers, competitors, and people who want to be heard by anyone within a mile radius.
Smart alternator that reads the amperage needed and only produces what's necessary to run your system, even when the car is in idle. It uses BJT (Bipolar Junction Transistor), Mosfet, and PWM (Pulse Width Modulation) technology to control it's power.
Includes an on/off switch as well as a knob that controls voltage from 14-19V shown on a digital display. Built in temperature sensors to protect the alternator preventing their destruction. These features allow you to have full control at your fingertips. This is equipped with a heavy duty external regulator that will shut off before allowing damage to the alternator. If this alternator fails for any reason all you have to do is replace the regulator and you'll be up and running in less than one minute.
