Alpine R-A75M : 750W Mono Automotive Amplifier, 750W/500W Mono @ 2Ω/4Ω

The R-Series amplifiers utilize Alpine’s advanced amplifier platform that takes the classic Class-D amplifier circuit and adds dual post-filter feedback loops for unmatched accuracy and control. This technology., originally launched in the premium X-Series amplifiers,, produces efficient power with enhanced dynamic range, qualifying the R-Series amplifiers to be Hi-Resolution Audio compliant.  This new technology minimizes audible imperfections like excessive phase shift and internal noise which can deteriorate sound quality. With an incredibly low phase shift of 46°, the R-A60F 4-channel amplifier delivers accurate imaging compared to well over 100° of phase shift by a competitive amplifier model. This superior phase curve ensures a proper sound stage among the singers and instruments. R-Series amplifiers have a built-in bandpass filter which lets you design an active speaker set-up without a separate processor. Improve the sound quality of component speakers by ditching your passive
