  • 8-channel amplification powers a complete front and rear system with one unit

8-Channel Hi-Res Amplifier Bundle

The Alpine PXE-C80-88 OPTIM8 combines an 8-channel amplifier with high-resolution digital sound processing for factory or aftermarket head units. It provides real-time sound tuning via PC or iPhone app for precise adjustments. The bundle adds R2-S65 coaxial speakers and R2-S653 3-way component speakers for a complete system.

8-Channel Amplification for Multi-Speaker Layouts

The built-in amplifier drives eight independent channels to power front, rear and component sets simultaneously. This channel count matches the included coaxial and component speakers without needing extra amplifiers. Builders requiring more than eight channels must add separate amplification.

Hi-Res Certified Speakers with Glass-Fibre Cones

The R2-S65 and R2-S653 speakers carry Hi-Res Audio certification and use glass-fibre reinforced cones for accurate reproduction. The 3-way component set separates frequencies across dedicated drivers for improved imaging. Buyers needing shallow-mount speakers or different diameters must select alternative models.
