Alpine PXE-C80-88 OPTIM8 8-Channel DSP Bundle

This bundle combines an 8-channel digital sound processor amplifier with two 12-inch shallow subwoofer enclosures and two 6x9-inch coaxial speakers. It is built for drivers who want a complete, pre-matched audio upgrade from a single package. The system suits factory or aftermarket head units needing amplification and detailed tuning control.

Real-time tuning via PC or iPhone app

The processor handles variable-resolution impulse response for high-resolution audio sources. Its shallow subwoofer enclosures measure only 5.25 inches deep, limiting placement to spaces that can accommodate that depth. Eight channels of amplification restrict the system to configurations that fit within that channel count.

Replaces separate amplifier, DSP.

The all-in-one design removes the need to match individual components for power and impedance. The jump is worth it when installation space is tight and a unified tuning interface is preferred over assembling discrete parts. Buyers needing more than eight channels or deeper enclosures should look elsewhere.

Questions about this item

Should I choose the 12-inch subwoofers or the 6x9-inch speakers for my system?

This bundle includes both — two 12-inch shallow subwoofers for deep bass and two 6x9-inch coaxial speakers for full-range sound — so you do not need to choose between them.

What does the 8-channel amplifier actually deliver when installed?

The 8-channel amp powers all four speakers in this bundle — two subwoofers and two 6x9s — from a single chassis with built-in DSP tuning via PC or iPhone app.

How does the 5.25-inch shallow enclosure depth affect installation?

At only 5.25 inches deep, the subwoofer enclosures fit in tight spaces such as under seats or in spare-tire wells while still housing a full 12-inch driver.
