All ZX Amps are now outfitted with differential RCA inputs.

Add a remote bass control to easily tweak your sound on the fly.

ZX-Series Amplifiers return for 2008 as reliable as ever–21 no-fault options to run a complete car audio system. Two-channel, four-channel, three- and five-channel hybrids, and absurd single-channel subwoofer amps round out a hard-working, noise-free lineup known for supplying the force until the listener shuts the music down. And now all ZX Amps are outfitted with differential RCA inputs, completely eliminating unwanted whines and audio trash and making for the most enjoyable listening experience possible. Differential inputs and new automatic turn-on modes make ZX Amps some of the most complete power producers on the market.

ZX Multi-Channel and Hybrid Amplifiers
Six ZX-Series Multi-Channel Amplifiers put the choice of system installation in your hands. Power ranges from 50 watts x 4 channels up to 215 watts x 4, giving the user plenty of system decisions to make. These amps carry the same crossover and KICKEQ Bass Boost as the stereo amps, but they also include a useful fader dial. Two popular hybrid models among the multi-channel amps feature a sub-rattling, 420-watt Class D channel to go along with 85 watts/channel in the ZX.3 amp and the 85 watts x 4 in the ZX.5 amp. Boost remains available, but through the sub sections only.

ZX350.4 Features

  • 3 automatic turn-on modes
  • Balanced differential inputs for noise elimination
  • RCA inputs have direct speaker level input capability
  • Easily removable top allows for custom painting
  • Optional end caps
  • 2 ohm stability on all amps
  • Angled power connections

Onyx amps include a remote subwoofer level control.

Four-Channel or Bridged Mode
Run in four-channel mode for 750 Watts x 4 peak power at 2 ohms (300 Watts x 4 at 4 ohms) or bridge at 4 ohms for 1500 Watts x 2 peak.

Trimode Operation
This allows you to send your signal to a tri-way crossover for adding a subwoofer to the front/rear two-channel output.

Remote Subwoofer Level Control
Onyx amps include a remote subwoofer level control. If you’re using it to power a sub, you’ll be able to quickly make level adjustments.

Line/Speaker Level Inputs
Separate line and speaker level inputs mean the Onyx can handle high-level signals from receivers lacking RCA outputs.

Built-In Crossovers
This amplifier features variable high- and low-pass crossovers, so you can adjust the sound to suit whatever speakers you’re driving.

Variable Gain Controls
Allows you to match the input gain to your receiver for better sound with less distortion.

MOSFET Power Supply
For high performance with low heat.

Bass Boost
Add a little extra low-end power with 0 to +18dB of variable bass boost.

Power and Protection LEDs
Protection LEDs let you know when there’s a problem.
