Patented Smart Engage Technology
Easiest way to connect after market amplifiers to factory audio systems
Connect directly to the factory head unit via RCA cables or directly to the high-level speaker inputs.
Eliminates the need to remove the head unit during installation because signal can be taken from anywhere along the speaker wire run.
The Smart Engage circuit in the amplifier senses the voltage through the speaker wire once the stereo is turned on and automatically turns the amplifier on, this eliminates the need for a remote turn-on wire.
Patented Pure N-Channel Technology
N-Channel MOSFETS on both the positive and negative side of the amplifiers output stage
N-Channel MOSFETS are less resistant which means less power is wasted as heat.
Both the positive and negative circuits have equal Usable Power Ratings so the speaker is better controlled and more linear.
Xtant Technologies Cooling
Thermal regulated, amplifier intercooler
Controlled by the output volume and temperature
Fan draws cool air in through intake and moves it through the internal heatsink where it cools the internal devices as it pushes hot air out through side vents.
Allows the amplifier to play louder and longer without thermal breakdown.
Clean Aesthetics
Concealed feature set and wiring interface.
All controls and wiring connections are hidden behind removable panels.
Panels are magnetized to remain in place but can be easily removed to make adjusts to controls and wires.
Real Wood
Amplifiers ship with real wood inserts that can be stained to match vehicle interiors.
Audiophile Mode
Direct through put of signal from source to speaker.
Delivers true signal to the speakers for the ultimate listening experience.
Eliminates component noise in the signal path.
