DS18 ELITE ZXI.4 Full-Range 4-Channel Class D Amplifier 125 Watts x 4 @ 4-Ohm RMS
Over time evolution is inevitable. The same can be said for DS18's new Z series model of amplifiers! We took one of our best selling lines and upgraded every aspect of it. They now put out even more power, have more top of the line components, and are guaranteed to deliver amazing quantities of RMS power on demand. The previous Z series was very powerful to begin with and we packed all new DS18 branded boards with much more efficient electronics, and with all new heat sync casings to make an amazing amp line even more perfect for your needs. You have your pick of multiple 2 channel, 4 channel, and Monoblock amps in this line to power every aspect of your DS18 audio system.
Highlights
- Elegant design that retains very high durability with incorporated high efficiency heat sync.
- High quality circuit board to give the most power with the highest efficiency rate providing high power on demand.
- Easily tuned crossover and gain controls for the perfect sound settings in your vehicle.
