Features

Mono-Power Amp Design: The Infinity Reference 6001A is designed with specific features to power subwoofers, providing 350W RMS @ 4Ω and 600W RMS @ 2Ω. This amplifier is not designed to power a full-range speaker.

Class D Design: The Infinity Reference 6001A is equipped with a high-performance Class D switching power supply, which is more efficient than traditional class AB power supplies. This allows the amp to provide high output with less current draw from your vehicle's charging system.

Low Noise & Distortion: The 6001A amplifier features balanced differential inputs to ensure low noise and distortion, even at high output levels. This also makes it less susceptible to line induced, radiated engine noise.

Protection Circuitry: The amp features 3-way protection, and will shut itself down in the following cases:

• Temperature: Amplifier is overheated
• Over/Under Voltage: Voltage at the +12V (Battery) terminal is less than 8.5V or more than 16V
• Short Circuit: Short circuit in speaker or speaker wire

Power and Protection LEDs: The amplifier features a Power and Protection LED on the input side of the unit. The Power LED illuminates Green when the amplifier is supplied power. The Protection LED will illuminate Red when the amplifier goes into protect-mode.

Compact Size: The Reference 6001A is housed in a compact chassis with a small footprint, allowing it to fit in more vehicles where mounting space is limited.

Controls

Hidden Control Panel: The top panel of the Reference 6001A can unsnap and slide off to access all of the amp's controls.

Gain: Rotary control to match the level of the preamp input signal

Low Pass Filter: The 6001A has a variable 12dB per octave, 32-320Hz low pass filter to prevent unwanted high-frequencies from reaching your subwoofers so they can play deeper and louder.

Bass Boost: The Bass Boost control allows you to enhance the bass output of your system at 45Hz with an adjustment range of 0-12dB.

Phase Switch: Allows you to select normal or reverse for best bass.

Turn-On Mode: Lets you select whether you are using high- or low-level input signals.

• DC: Allows the amp to power on/off with speaker-level signals.
• REM: Allows the amp to power on/off when the REM terminal gets +12V from the headunit's remote output. This should be selected when using the RCA low-level inputs.

Input Level: Working in conjunction with the Turn-On Mode, this 3-way switch lets you set the input sensitivity range:

• Lo: Set to this when using RCA low-level inputs.
• HI1 & HI2: These settings provide 2 levels of input sensitivity when using speaker-level inputs. If the amp doesn't power on when set to HI1, setting it to HI2 will allow it to be activated.

RBC Remote Level Control: The amp has an RJ-25 jack for use with the included RBC (Remote Bass Control) remote sub-level control module. The control module includes a 16.5' cable to connect the remote to the amplifier. This sub-level controller allows the subwoofer level to be adjusted from the listening position and includes hardware to mount it under the dash.

Connections

Preamp & Speaker Input: A single pair of RCA jacks is used for both low-level and high-level signals. If using high-level, 2 speaker wire-to-RCA adapters are provided. These feature an RCA plug on one end and 2 wire ports with set-screws on the other end. These can accept up to 18 ga. speaker wire.

Speaker Output: Features 4 set screw terminals for connecting speaker wires; accommodating up to 8 ga. (16 ga. minimum recommended).

Remote Level Control: RJ-25 socket for use with the provided RBC remote sub-level control.

Power:

• +12V: Set screw terminal for power wire from battery; handles up to 4 gauge wire (8 gauge minimum recommended)
• Remote: Set screw terminal for remote turn-on lead; handles up to 8 gauge wire (18 gauge minimum recommended)
• Ground: Set screw terminal for ground; handles up to 4 gauge wire (8 gauge minimum recommended)

Fuses: 2 Slots for 30A ATC fuses (installed). Two spare 30A fuses are also provided.
