High Currrent Amplifiers


STABILITY
Audiobahn is one of the few manufacturers to be reputed for selling power-hungry

High Current amplifiers. These competition amplifiers utilize an advanced power supply

to help increase the stability of their traditional AB MOSFET circuitry. This means

High Current amplifiers can operate at much lower impedances and output more

power than traditional AB MOSFET amplifiers. Audiobahn High Current amplifiers

are stable to impedances as low as 1 ohm mono, which allows them to drive

maximum power to any component in your vehicle’s sound system. Audiobahn

also employs unregulated power supplies. This means the higher the voltage of

your electrical system, the more power the amplifier will produce, making them ideal

for competition as you can run up to a 17.9 volt system for maximum power output.

ANALOG VU METERS
Giving this series an added element of control, all Audiobahn High Current amplifiers

feature analog VU meters. This visual indicator lets you see the decibel level output

of your vehicle and how much power is going to the speakers. Monitoring both left and

right channels, the VU meter is visible in the dark thanks to cobalt blue LED illumination,

a staple of nearly all Audiobahn products.

4-WAY PROTECTION CIRCUITRY
All Audiobahn amplifiers feature 4-way protection circuitry. This protection circuitry is

designed to defend the amplifiers from thermal overload, internally-contained short circuits,

voltage overload and DC offset. 4-Way protection ensures that these amplifiers will continue

to operate despite the “real world” mishaps that can occur in the mobile audio environment.
