Infinity’s Reference 3004A amplifier will add plenty of muscle to your music without breaking a sweat, and it’ll look good doing it. This 4-channel powerhouse delivers 75 watts RMS to each of the front and rear speakers in your car. You could use this amp in 2-channel mode now to drive a couple subwoofers with 200 watts RMS each, then reassign it to your front and rear speakers when you get a bigger sub amp. Speaker-level inputs allow this amplifier to work in almost any system, even if you’re keeping your car’s factory radio. You can use the separate high- and low-pass filters on the front and rear channels to maximize the performance of your speakers or subs. 75 watts RMS x 4 at 4 ohms (100 watts RMS x 4 at 2 ohms). 200 watts RMS x 2 at 4 ohms in bridged mode (4-ohm stable in bridged mode). Variable high- and low-pass filters (32-320 Hz, 12 dB/octave) on front and rear channels. Preamp and speaker-level inputs. Fuse rating30A x 2. 8-gauge power and ground leads recommended – wiring and hardware not included with amplifier. WxHxD=320mm x 55.5mm x 180mm WxHxD=12-5/8″ x 2-3/16″ x 7-1/8. 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 Infinity’s Reference 6001A mono subwoofer amplifier will add some bass muscle to your music without breaking a sweat, and it’ll look good doing it. This powerhouse delivers 600-Watts RMS to your subwoofer, and its Class D design ensures the amp’s high output will put minimal strain your vehicle’s electrical system. Speaker-level inputs allow this amplifier to work in almost any system, even if you’re hanging on to your factory radio. You can use the low-pass filter and variable bass boost to maximize the performance of your subwoofer and enclosure, while a phase switch ensures that the bass will blend well with your full-range speakers. 350 watts RMS x 1 at 4 ohms (600 watts RMS x 1 at 2 ohms). Class D amp technology. Variable low-pass filter (32-320 Hz, 12 dB/octave). Variable bass boost (0-12 dB at 45Hz). Phase switch (0, 180 degrees). WxHxD=220mm x 55.5mm x 180mm WxHxD=8-11/16″ x 2-3/16″ x7-1/8. 4-gauge power and ground leads recommended – wiring and hardware not included with amplifier. WxHxD=360mm x 55.5mm x 180mm WxHxD=14-3/16″ x 2-3/16″ x7-1/8. 600w RMS / 1200W MAX. The Reference 6001A amplifier features a low-profile chassis and a small overall footprint to fit in more vehicles where available space is limited. Speaker-level and low-level inputs allow the Reference 6001A to integrate with both aftermarket and factory car stereo systems. Variable crossover and bass boost. Unlike many amplifiers available at similar prices, the Reference 6001A features variable electronic crossovers and bass boost circuits allowing for precise system tuning and performance. Low noise and distortion. The Reference 6001A 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. 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. On-board circuitry protects the Reference 6001A from shorts, high-temperature, overvoltage and undervoltage. An LED indicator is provided to let you know when one of these conditions exists. This switch changes the input phase to inverted or non-inverted. The RBC wired remote is an easy installation and can be mounted for convenient volume adjustment from driver’s seat.
