Bundle Contents

This bundle combines an Alpine PXE-C80-88 OPTIM8 8-Channel Hi-Res DSP Amplifier with an SS-SB12 12" Shallow Subwoofer Enclosure and R2-S65 6.5" Coaxial Speakers. It provides a complete, matched audio upgrade for vehicles where space is limited but sound quality is a priority. The all-in-one amplifier simplifies installation by integrating processing and power.

Amplifier Capacity and Tuning

The 8-channel amplifier drives the included subwoofer and speakers while offering real-time tuning via PC or iPhone app. A 31-band EQ and automatic sound tuning allow precise adjustment for the cabin. The DSP handles hi-res audio playback and multiple inputs, but lacks wireless streaming or built-in source switching beyond the wired connections provided.

Upgrade Path and Fit

This system replaces a factory head unit and passive speakers with active processing and dedicated amplification. The 5.25" deep subwoofer enclosure fits tight spaces where standard boxes cannot. The 16.5 cm glass-fiber woofers and coaxial design upgrade door locations directly. Builders needing more than eight channels or a separate monoblock for additional subwoofers should look elsewhere.

Questions about this item

Will the PXE-C80-88 OPTIM8 8-channel amplifier work with my existing factory head unit?

Yes, the amplifier features multiple inputs including high-level speaker inputs that accept signals directly from a factory head unit without requiring a separate line-output converter.

How do I verify the 31-band EQ and automatic tuning are active after installing the DSP amplifier?

Use the PC or iPhone app to view the real-time EQ curve and tuning status; the app shows each of the 31 bands and confirms when automatic sound tuning has completed its measurements.

Does the bundle include all wiring needed for the SS-SB12 shallow subwoofer enclosure and R2-S65 6.5" coaxial speakers?

The bundle provides the PXE-C80-88 amplifier, SS-SB12 12" shallow enclosure, and R2-S65 6.5" speakers; power, ground, RCA, and speaker wire must be purchased separately.
