Compact size
Infinity Reference amplifiers have been engineered with a compact footprint to fit in more vehicles even if available space is limited.
High and low level input
Speaker-level and low-level inputs allow the Reference 3004A to integrate with both aftermarket and factory car stereo systems.
Variable crossover and bass boost
Unlike many amplifiers available at similar prices, the Infinity Reference 3004A features variable electronic crossovers circuits allowing for precise system tuning and performance.
Low noise and distortion
The Reference 3004A has been engineered using Balanced Differential Inputs to ensure low noise and distortion even at high output levels. This also makes it far less susceptible to line induced radiated engine noise.
Input Level Control
When low-level inputs are used, this control adjusts the input sensitivity between 200mVrms and 2.0 Vrms. When high-level inputs are used, this control adjusts the input sensitivity between 2Vrms and 20Vrms.
Full on-board protection
On-board circuitry protects the Reference 3004A from shorts, high-temperature, overvoltage and undervoltage. An LED indicator is provided to let you know when one of these conditions exists.
Preamp Outputs
Using multiple amplifiers, the Reference 3004A has full range preamp outputs allowing you to feed an additional amplifier without using splitters.

- Fuse Rating : 30x2 A
Features:
- 4-Channel Design: The Infinity Reference 3004A is designed to provide 75W RMS x 4 channels @ 4Ω and 100W RMS x 4 channels @ 2Ω. Both front and rear pairs of channels can be bridged into a 4Ω load, providing 200W RMS x 2.
- Class H Design: The Infinity Reference 3004A is equipped with high-performance Class H amplifier topology. Class H is designed to provide sound quality approaching Class AB, while providing Class D type efficiency and low-power consumption.
- Low Noise & Distortion: The 3004A 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
- 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 3004A is housed in a compact chassis with a small footprint, allowing it to fit in more vehicles where mounting space is limited.
- Hidden Control Panel: The top panel of the Reference 3004A can unsnap and slide off to access all of the amp's controls.
- Gain: Both front and rear pairs of channels have their own rotary control to match the level of the input signal
- Filter & Frequency: Both front and rear channels can have a crossover applied to them. A 3-way switch for each lets you select: HPF (high-pass), LPF (low-pass), or FULL (full-range). This variable 12dB per octave filter includes a Freq dial that can be set between 32Hz and 320Hz.
- Turn-On Mode: Lets you select whether you are using high- or low-level input signals.
- Input Level: Working in conjunction with the Turn-On Mode, this 3-way switch lets you set the input sensitivity range
- Preamp & Speaker Input: Two pairs of RCA jacks are used for both low-level and high-level signals. If using high-level, 4 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, accepting speaker wire up to 18 ga.
- Preamp Outputs: A pair of RCA output jacks are provided to pass the incoming signals out to additional amplifiers, without the need for RCA splitters.
- Speaker Output: Eight set-screw terminals for connecting speaker wires; accommodating up to 8 ga. (16 ga. minimum recommended).
