Alpine introduces the all-new S-Series amplifiers - a perfect match to the S-Series speakers. These amps have an excellent Watts-per-Euro ratio in the Class-D category, feature a very high heat resistance and won’t shut down due to overheating. They also feature excellent sound quality in their price range. Three new S-Series amplifiers join the S-Series family, known for reliable performance and value-oriented products. All three S-Series amps (mono, 4-channel and 5-channel) contain technology currently implemented in R and X-Series models. The S-Series amps feature attractive prices and are designed to perform perfectly with the existing S-Series speakers.
