Name: Alpine - R-Series Class D Bridgeable Multichannel Amplifier with Variable Crossovers - Black
Brand: Alpine
SKU: 6542081
Rating: 5 (1 reviews)

Key Specs
- Continuous Watts x Channel @ Ohms: 100W x4 @ 4 ohms
- Maximum Watts x Channel @ Ohms: 150 watts RMS x 4 @ 2 ohms (This is the maximum load the speaker, subwoofer or amp can drive.)
- Amplifier Class: D (An amplifier's mode of operation, specifically the conditions in which its electrical current flows for the duration of an audio signal, determines its class. Each class has its strengths and weaknesses when it comes to power efficiency, levels of crossover distortion, and overall sound quality.)
- Number Of Channels: 4
- Bass Boost: None (Circuitry that boosts the bass response of the amplifier, improving audio reproduction enhancing the sound of low frequencies. Fixed boost means the level of bass response is preset, whereas variable boost allows the user to make adjustments.)
- Bridgeable: true (Bridging an amplifier increases the power it supplies to the speaker(s).)
- Low-Pass Crossover: Variable (Devices with this function allow only audio frequencies below a chosen cut-off frequency to pass through to a speaker or sound system. A device may have a cut-off frequency predetermined by its manufacturer (fixed), multiple cut-off frequency options to choose from (selectable), or have the capability for the frequency to be configured by the user (variable).)
- High-Pass Crossover: Variable (Devices with this function allow only audio frequencies above a chosen cut-off frequency to pass through to a speaker or sound system. A device may have a cut-off frequency predetermined by its manufacturer (fixed), multiple cut-off frequency options to choose from (selectable), or have the capability for the frequency to be configured by the user (variable).)
- Speaker-Level Inputs: true (Also referred to as high-level inputs. Enables the amplifier to receive a sound signal from another device that does not have RCA, or low-level, inputs.)

Audio
- Number Of Channels: 4
- Minimum Frequency Response: 10 hertz (Describes the maximum range of frequencies or musical tones a product can reproduce, from very low tones to very high treble tones. The minimum frequency or musical tone the speaker can reproduce. High treble tones have higher frequencies while low tones and deep bass have lower frequencies.)
- Maximum Frequency Response: 45 kilohertz (Describes the maximum range of frequencies or musical tones a product can reproduce, from very low tones to very high treble tones. The maximum frequency or musical tone the speaker can reproduce. High treble tones have higher frequencies while low tones and deep bass have lower frequencies.)
- Signal-to-Noise Ratio (SNR): 80 decibels (The ratio of the desired signal's strength to the level of background noise. A ratio higher than 1:1, which equates to greater than 0 decibels, indicates more signal than noise.)
- Bass Boost: None (Circuitry that boosts the bass response of the amplifier, improving audio reproduction enhancing the sound of low frequencies. Fixed boost means the level of bass response is preset, whereas variable boost allows the user to make adjustments.)
Features

Listen to your favorite Hi-Res music and podcasts with this Alpine four-channel amplifier. The Next-Generation R-Series Amplifiers are Hi-Res Audio Certified and able to reproduce up to 45kHz frequency response. This ultra-wide bandwidth brings music even closer to the original source while the classic R-Series design maintains the “loud and fun” performance quality that long-time fans have come to enjoy. The R2-A60F features a reduced footprint that’s 15% smaller than the previous model (R-A60F), making it easier than ever to install in most vehicle applications while still getting the same powerhouse performance.

Robust power output: RMS rating of 150W x 4 @ 2 ohms, 4 channels driven for robust audio.
Variable high-pass, low-pass, and bandpass filters on front & rear channels: Ensure flexible operation
4 ohms impedance: Conducts power evenly to keep the speaker at an appropriate level.
Versatile channel modes: Use in 3-channel mode, driving a pair of speakers with the front channels and bridging rear channels to send up to 300 watts RMS to a subwoofer
4-channel output: Allows easy system expansion.
Class D circuitry: Ensures reliable power handling and it is small enough to fit in almost any location
Hi-res capable: Frequency response: (+0/-3 dB) 15 to 45,000 Hz (Hi-Res capable)
Smaller footprint: 15% smaller than the previous model, making it easier to install in most vehicle applications without sacrificing performance
Simplified installation: Speaker connections are all on one side, and controls moved to top for convenient access
