Rockford Fosgate Amplifiers (78)

Rockford Fosgate Prime R2-500X1 500W Prime Series Monoblock Subwoofer Class D Amplifier Primed for performance, the R2-500X1 amplifier is a 500 watt, class-D, capable of operating at 4Ω or 2Ω mono. This amplifier is extremely efficient because of its class D technology which reduces demand on the vehicle's electrical system. The amp also features C.L.E.A.N. circuitry to help you adjust your gain settings, a P.O.W.E.R. Supply that generates more power as voltage increases, and integrated Punch EQ that corrects for acoustic deficiencies while delivering up to 3X the bass. For subwoofers, a variable infrasonic filter and remote level control allows you to tune the bass for the desired level for the music.

Rockford Fosgate Punch P400X4 4-channel car amplifier 50 watts RMS x 4 Big power for your speakers or subwoofersRockford Fosgate's Punch P400X4 amplifier can put 50 watts RMS to each of your front and rear speakers, which is plenty of power for clean music even at high levels. You can use the amp's high-pass filter to remove low bass from your speakers, so they'll play more efficiently. You can also switch this amp into 2-channel mode to drive a couple of subwoofers with up to 200 watts RMS each. The amp's low-pass filter is handy for getting the right sound from your sub/enclosure combo. The Punch EQ2 includes bass and treble boosts if you want to add some boom and sizzle back into the mix. Easy to set for optimum performanceOnce again, Rockford Fosgate steps away from the crowd with their C.L.E.A.N. technology (Calibrated Level Eliminates Audible Noise). This setup system ensures your music will sound as clean and powerful as possible. It works like this: first, download the setup tones from Rockford Fosgate, then play the tone, adjust the receiver volume until a red clip light on the amp goes out, then turn the amp gain up until a blue light comes on. It's that simple — your amplifier will be perfectly set to match your receiver's output. When your receiver reaches maximum clean volume, you'll get maximum clean power from your Power amp. You'll hear less background noise and more of your music at quiet listening levels. Keeps an eye on things while playingIf that blue light turns solid red while you're playing music, the amp tells you that your source is distorting, and you should turn it down or risk damage to your gear. The amp's built-in computer keeps tabs on the output current, ensuring that plunging speaker impedances (they change during play) or a short circuit won't hurt anything. Maintaining coolness raises efficiency and lowers distortion.Rockford Fosgate's Dynamic Thermal Management system uses forced air to dissipate heat evenly across the amp and out through the high mass heatsink, efficiently drawing heat away from vital internal parts. Their proprietary MEHSA cooling process maximizes the heat transfer from the MOSFET devices to the heatsink, allowing the heat to escape more readily, so the transistors stay cooler and work better. General Features: 4-channel car amplifier 50 watts RMS x 4 at 4 ohms (100 watts RMS x 4 at 2 ohms) 200 watts RMS x 2 bridged at 4 ohms (4-ohm stable in bridged mode) CEA-2006 compliant variable high- and low-pass filter (50-250 Hz, 12 dB/octave) variable PEQ2 bass/treble boost (0-18 dB at 45 Hz and 0-14 dB at 12.5K Hz) C.L.E.A.N. gain setup system includes clip lights and links to Rockford Fosgate's setup tones Class-AB amplifier design frequency response: 20-20K Hz Dynamic Thermal Management and MEHSA MOSFET cooling systems MOSFET power and output stages preamp and speaker-level inputs (speaker wire to RCA adapter required for speaker-level input) signal-sensing turn-on with speaker-level inputs eliminates the need for a remote turn-on lead 4-gauge power and ground leads and a 60-amp fuse recommended — wiring and hardware not included with amplifier 11-1/8"W x 2-7/16"H x 8-13/16"D warranty: 1 year Warning:This product can expose you to chemicals known to the State of California to cause cancer.
