  • Hi-Res Audio certified speakers reach 40kHz frequency response
  • Real-time sound tuning via PC or iPhone apps
  • Glass-fiber reinforced cones on all speakers for accurate reproduction

Bundle Contents

This package combines an Alpine PXE-C80-88 OPTIM8 8-channel digital sound processor amplifier with two speaker sets. It delivers 50W x 6 plus 300W x 2 at 2 ohms. The R2-S65 coaxial pair and R2-S652 component pair both use 6.5 inch glass-fibre cones and are Hi-Res Audio certified to 40kHz.

Installation Notes

The amplifier fits behind many dashboards and connects via high-level or RCA inputs, while the PC and iPhone apps guide real-time tuning. The component set requires a separate 4.3 cm tweeter mounting location, which may need custom fabrication in some door panels. Coaxial speakers drop into standard 6.5 inch openings with minimal modification.

System Limits

The eight-channel DSP handles time alignment, crossover and EQ for each output, but processing resolution tops out at 40kHz. Total continuous power is distributed across six mid-range channels and two subwoofer channels at 2 ohms. Adding more speakers would exceed the available channels and require a second processor.

Questions about this item

How can I confirm the PXE-C80-88 OPTIM8 is processing Hi-Res audio correctly after installation?

Use the PC or iPhone app to view real-time tuning data and verify the processor shows active 8-channel output at the rated 50W x 6 and 300W x 2 into 2 ohms.

Which speakers and cables are included in the box, and what must I source separately?

The bundle supplies the PXE-C80-88 processor, one pair of R2-S65 6.5" coaxial speakers and one pair of R2-S652 6.5" component speakers with 4.3 cm tweeters; amplifier wiring kits and speaker wire are not included.

Should I choose the R2-S65 coaxial set or the R2-S652 component set for my doors?

Both pairs are supplied together — the R2-S65 coaxials fit standard 6.5" locations while the R2-S652 components add a separate 4.3 cm tweeter for improved staging; install both for full system coverage.
