Alpine S2-A36F S-Series Class-D 4-Channel Amplifier, Hi-Res Certified, 60W x 4

Alpine S2-A36F Alpine's Next Generation S-Series S2-A36F 4-channel amplifier delivers 60 watts RMS of pristine high-fidelity signal to each of your car's front and rear speakers, adding sweet, clear sound to your ride. The amp's extended high-frequency response brings your music to life, with its precise details and emotional power clearly revealed. 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 an optional wired remote to control the level of the rear channels from your front seat. More convenient features 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 one 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.  Product highlights: 4-channel car amplifier 60 watts RMS x 4 at 4 ohms 90 watts RMS x 4 at 2 ohms 180 watts RMS x 2 bridged at 4 ohms Hi-Res Audio Certified (frequency response: 20-40k Hz) variable high- and low-pass filters (50-400 Hz, 12 dB/octave) variable mid-bass boost (0-12 dB at 100 Hz) on Ch 3/4 optional wired remote available for Ch 3/4 More info: preamp and speaker-level inputs speaker-level inputs handle up to 10V RCA adapters required for speaker-level input signal-sensing turn-on with speaker-level inputs wiring and hardware not included with amplifier 8 gauge power and ground leads recommended fuse rating: 40A x 1 dimensions: 8.66"W x 2.21"H x 8.3"D warranty: 1 year
