Alpine PXE-C80-88 OPTIM8 8-Channel Bundle

This bundle combines an 8-channel digital sound processor amplifier with a shallow 12-inch subwoofer enclosure, 6x9-inch coaxial speakers, and a 6.5-inch 3-way component speaker set. It is designed for car audio enthusiasts who want a complete, high-resolution system upgrade from a single package. The all-in-one processor amplifier simplifies system architecture by integrating amplification and signal tuning.

8-Channel Hi-Res Processor with Auto Tuning

The PXE-C80-88 OPTIM8 unit provides eight channels of amplification and high-resolution audio processing in one chassis. Automatic sound tuning is performed via a PC or iPhone application, removing the need for external measurement hardware. Multiple EQ options and crossover networks allow precise adjustment for each speaker location in the vehicle.

Shallow Subwoofer Fits Tight Spaces

The SS-SB12 enclosure uses a shallow-profile design to fit behind seats or in cargo areas where standard boxes cannot go. Adjustable mounting brackets help align the enclosure in irregular spaces. Component speaker installation requires running separate tweeter, midrange, and woofer wires to the PRO crossover networks, which adds wiring complexity compared to coaxial sets.

Questions about this item

How does the 80-watt per channel output translate to real-world volume and headroom?

The 80-watt per channel amplifier drives the included component and coaxial speakers cleanly at high volumes while reserving headroom for dynamic peaks in Hi-Res audio tracks.

What does the 8-channel digital sound processor actually control in this system?

The processor handles time alignment, crossover points and EQ for all eight channels, tuning the subwoofer, component set and coaxial speakers together from a single app.

Will the shallow 12-inch subwoofer enclosure fit under a standard rear seat or in a compact boot?

The SS-SB12 shallow-mount enclosure is designed for tight spaces and includes adjustable mounting brackets so it can slide under seats or sit flush against a boot floor.
