Alpine S2-A36F 600W Next Generation S-Series Hi Res Class-D 4-Channel Car Amplifier The next generation of Alpine S-Series amplifiers is designed to take your car audio experience to the next level without breaking the bank. With a sleek new redesign and upgraded features from their predecessors, these amplifiers offer exceptional performance and power on an affordable budget.The S-Series S2-A36F 4-channel amplifier delivers 60 Watts RMS @4 Ohms or 90 Watts RMS @2 Ohms of pristine high-fidelity signal to your car's front and rear speakers, adding sweet, clear sound to your vehicle.The amp brings your music to life by being Hi-Res Audio certified, with its precise details and emotional power revealed with a frequency response up to 40kHz. For a 3-channel 2-way system, you could also use the amp to drive a pair of front speakers with 60 Watts RMS each while powering a subwoofer with 180 Watts RMS from the bridged rear channels. A variable mid-bass boost on those rear channels allows you to dial in some extra kick and impact to your system's low-frequency sound. You can even add the optional wired remote RUX-KNOB2 to control the level of the rear channels from your front seat.High- and low-pass filters put you in command of the frequency spectrum that reaches your speakers and subs. The amp includes preamp- and speaker-level inputs so you can install it in almost any vehicle, even with a factory radio. When using the speaker-level inputs, the amp can sense the incoming signal and turn itself on, eliminating the need to run a separate turn-on wire to the receiver or fuse box.

Power Acoustik MOFO4-3KD 3000 Watts MOFO Series 4 Channel Class D Car Amplifier For decades, car amplifiers have been repetitiously manufactured having a common horizontal shape. While practical, this stereotypical form factor has gone stale. End caps & trim bezels do their best to spruce up lifeless heatsinks. However, at the end of the day, this lack of creativity might leave you desiring more. It’s time to break these stubborn habits and set in motion a new trend in amplifier design. MOFO amplifiers depart from the mundane squatty shape of conventional amplifiers, bringing the character back to amplifier design. A diecast aluminum 4-leg pedestal secures a compact 5”x5” MOFO tower chassis, leaving ample floor space in any trunk or cargo space. You could even attach MOFO amps to wall panels with an included wall-mount bracket. Keeping up with your demands, MOFO amps use advanced high-current power supplies and Class D output topology delivering power beyond your wildest dreams… General Features: 5” Square Monolith Chassis Design for Installation Versatility Die-cast Aluminium 4-leg Pedestal for Vertical Installation Mounting Bracket for Wall or Horizontal Mounting Included 2-ohm Stability Accommodates Various Speaker Configurations Direct Short, Thermal, & Overload Circuits Protect Amplifier 200mv-6V Low-Level RCA Input Accepts Balanced Signal Variable 12dB/Octave High Pass & Low Pass Crossovers 8ga Power/Ground Wire Terminals, 4ga Adapter Included 8ga Direct Connect Speaker Output Wire Terminals Maximum Power: 3000 Watts Low-Frequency Response: 40 Hz High-Frequency Response: 3000 Hz Number of Channels: 4 Frequency Response: 40-3000 Hz Built-In Crossovers: Yes RMS Power Output: 250 Watts RMS Power Range: 500 Watts Amplifier Class : D Warning:This product can expose you to, known to the State of California to cause cancer.
