The new Z-ST200A AT voltage regulator/stabilizer provides a very stable, high-quality power supply, what that car audio systems need most, especially in racing environments. This power unit can provide a stable power supply of up to 200A and 3000W RMS, you can regulate your voltage from 12V up to 19V (with xtreme caution given the risk of breaking the amp). At 14.4V you will already have 50% more power, which translates into much more dynamics.
