About the Audiobahn A6004T
If you want Audiobahn performance in a smaller package, check out the Intake series amps! A built-in air intake and a cooling fan ensures that these compact workhorses will stay cool through hours of heavy use. The 4-channel A6004T pumps out 75 watts RMS of MOSFET-fueled Class AB power to four speakers, or 300 watts x 2 in bridged mode perfect for a pair of subs.
You get the precise sonic control that you expect from Audiobahn. Variable high- and low-pass crossovers trim unwanted frequencies to adapt the amp for a variety of applications. You can improve the efficiency of your speaker system by adjusting the subsonic filter (variable from 20 to 50 Hz) to block low frequencies that your speakers can't reproduce. Switch on the bass boost to bring on a bass-quake!
Like to be in control? The optional remote-mount digital voltmeter lets you keep an eye on power levels from the driver's seat, while the optional wired remote bass boost provides variable control over your low-frequency punch.

Class A/B MOSFET Power Amplifier: The Audiobahn A6004T is a Class A/B amplifier that uses MOSFET high-speed switching devices for its amplification stage and power supply.
High-gloss Chrome-plated Finish: This amplifier has a high-gloss chrome-plated finish. A pair of white cotton gloves is included with the amplifier to prevent fingerprint smudges when handling and mounting the amp.
Cooling Fan: This amp has a built-in air intake and a cooling fan on top, ensuring cool, reliable operation.
Variable Subsonic Filter: The subsonic filter (variable from 20Hz to 50Hz) allows the amplifier to block ultra-low frequencies that your speakers can't reproduce, improving the efficiency of your speaker system. The front (1 & 2) and rear (3 & 4) channels have independent subsonic filters. No slope information is given for the subsonic filter.
Internal Crossovers: The front and rear channels have separate crossovers. Each crossover can be independently set for low-pass, high-pass, or full-range operation. In low-pass mode, the crossover is adjustable from 50Hz to 120Hz. In high-pass mode, the crossover is adjustable from 50Hz to 750Hz. In both modes, the crossover has a slope of 18dB/octave.
Bass Boost: The front and rear channels each have a bass boost switch which allows you to select a +18dB gain in bass output, centered at 50Hz. If you connect the optional ABR-100T remote bass boost control (item # 037ABR100T), the gain is adjustable from 0dB to +18dB.
Soft-Start Circuitry: The amplifier automatically turns on a few seconds after you turn your vehicle's ignition switch to ACC or ON. This eliminates the potentially damaging loud "thump" when multiple components power up simultaneously.
Optional Digital Voltmeter: This amp can be used with an the optional ADM-100T remote-mount digital voltmeter (item # 037ADM100T).
Protection Circuitry: This amp has 4-way protection circuitry, and will automatically shut down when it detects one of the following conditions: excessive heat (+158°F), input overload, short circuit, or DC offset. The protection LED will glow to indicate a problem that needs to be rectified.
Set-Screw Terminals: The A6004T is equipped with nickel-plated set-screw terminals for power and ground that can accept up to 4-gauge bare wire. The remote turn-on and the speaker output set-screw terminals can accept up to 8-gauge bare wire. Two Allen wrenches (3mm for power/ground and 2.5mm for remote turn-on and speakers) are supplied to tighten/loosen the set screws.
Line Outputs: The line outputs can be used to feed signals to another amplifier without having to split the signal or use Y-adapters. They are not affected by the built-in low-pass or high-pass filters.
Speaker-Level Inputs: Using the supplied speaker-level input harness, you can connect the amplifier to all 4 channels of a receiver or factory radio without preamp outputs. You will need to splice the receiver/radio's speaker wires to the harness, then simply plug the harness into the 5-pin high-input jack on the amplifier. Note: For 4-channel speaker level inputs, the 4 positive speaker leads and chassis ground are connected to the 5-wire harness.
DVM/Remote: Two female RJ-11 telephone-type jacks are provided for the optional Audiobahn ADM-100T remote-mount digital voltmeter and the ABR-100T remote bass boost control.
