The ZX Series. Competition and SPL Amplifiers.





The Zapco ZX Series Competition amps are designed to meet the needs of today’s “Street Challenge” cars that use multiple midrange and high frequency drivers to achieve high SPL in a sound quality car.  Dedicated SPL cars are designed to play only one frequency, but play it very loud. The Street Competition player wants  to get similar sound pressure with a system that has full spectrum sound. This type of system needs massive amounts of power, and with multiple speakers in each frequency range, it needs an amp that can play at low impedances.

The ZX is just that amplifier. The high current power supply and output devices of the ZX full range amps crank out 2,000 watts of power with full range, class AB sound quality.  All this power is available  in either a 2 Channel or a 4 Channel amplifier.

The ZX Series Class D bass amps are available  from 6,500 watts to over 20,000 watts. And make no mistake, these amps are not designed

just to be loud. This is Zapco power. These are Class D amps are designed to kick out rock solid, distortion free bass even at ear splitting volume levels.

If you want your car to sound like a concert at the outdoor amphitheater, the Zapco ZX Series is your amplifier.

Straight SPL cars need love too!  



Zapco knows that! In 2001 we built the amazing C2K-9.0XD that swept the dBDrag street classes in 2002, 2003, and 2004 and powered Team Puresound to a number of world records. This year we give you three new Class D amplifiers designed specifically for SPL competition. The SPL amps have almost all the same components as the SQL amps but the SPL amps thrive on 18 Volt electrical systems. This lets you pump extra power from the amps and avoids voltage drops when you’re burping  the system.  

The SPL amps are available at 5,500 watts (5.5KD SPL), 7,500 watts (7.5KD SPL), and 9,500 watts (9.5KD SPL).


So, great sound loud, or straight SPL…Zapco has your amplifier


When “too much, is just not quite enough”
