Alpine S-A32F - 4-channel amplifier digital

4-channel digital amplifier - 4 x 80W at 2 ohms

Alpine introduces the all-new S-Series amplifiers, perfectly matched to the S-Series loudspeakers. These amplifiers offer an excellent Watt/Euro ratio for Class-D amplifiers and are characterized by a very high heat resistance, which greatly reduces the risk of switching off due to overheating.

The S Series amplifiers are available in mono, 4-channel and 5-channel variants.
