Alpine 4-Channel Amplifiers (57)

Alpine S2-A36F 600W Next Generation S-Series Hi Res Class-D 4-Channel Car Amplifier + Absolute KIT4 4 Gauge Amp Kit 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.

Alpine KTA-450 4-Channel 200 Watt RMS Power Pack AmplifierDynamic Peak Power (DPP) Technology The KTA-450 features Alpine’s exclusive DPP technology which intelligently adjusts the gain to automatically adapt to musical needs. DPP prevents the amplifier from clipping music signals by supplying up to double the power to support rhythmic instruments that provide snappy sounds (like a snare drum, trumpet, or high-hat cymbals). During these dynamic musical passages, DPP instantly delivers bursts of power to rise to the peak demands of the music. The DPP technology boosts the KTA-450’s performance to 400 watts DPP, essentially doubling the amplifier’s power without increasing its size. Other Power Pack Amplifiers with the DPP technology are the KTA-30FW and KTA-30MW.
