In the Power Zone (PZ) Line, look for very reliable amplifiers with Crunch VersaCross Electronic Crossover. Amplifiers are available in 2, 4 and Mono configurations. Look for the two big models for systems that need 1 ohm stability.

Power Zone features some very special models for the PROS. These PRO models are engineered to make their biggest power into large, full range audio systems considered MOBILE-PRO installation. Power Zone Pro amps are perfect for parties in the park or tailgating. The Power Zone amplifiers produce a lot of power and with the QTD (Quick Thermal Dispersion) technology, assures the amplifier makes huge power while running very cool with nearly undetectable musical distortions.

Power Zone also offers three subwoofer mono models that are 1 ohm stable and include the bass remotes.
