Alpine OPTIM8 8-Channel Bundle

This Alpine bundle combines the PXE-C80-88 OPTIM8 8-channel digital sound processor amplifier with an SS-SB12 shallow subwoofer enclosure and R2-S69 6x9-inch coaxial speakers. It is designed for car audio enthusiasts who want a complete, matched system with integrated high-resolution processing and amplification. The package suits vehicles where space is limited but sound quality is a priority.

Sustained performance and tuning

The OPTIM8 processor provides real-time sound tuning via a PC or iPhone app using guided measurements for accurate calibration. Its variable-resolution impulse response maintains speed and accuracy during extended playback, while the 31-band EQ and anti-EQ for OEM systems manage frequency balance continuously. The SS-SB12 enclosure handles up to 300W RMS with its dual voice coil and neodymium magnet, and Gen2 DD-Linear Magnetic Circuit technology keeps bass controlled under load.

Installation considerations

The SS-SB12 enclosure measures only 5.25 deep, allowing it to fit in tight spaces with adjustable mounting options. The OPTIM8 unit includes digital inputs for versatile connectivity to factory or aftermarket sources. Buyers who need more than eight amplified channels or a larger subwoofer diameter should look elsewhere. Professional installation is recommended to configure the processor tuning and integrate the components correctly.

Questions about this item

How much power does the SS-SB12 subwoofer handle continuously during long listening sessions?

The Alpine SS-SB12 shallow enclosure is rated for 300W RMS power handling, so it can sustain that output all day without thermal issues.

Which wiring and signal sources do I need to connect the PXE-C80-88 processor amplifier?

You need speaker-level or line-level inputs from your head unit, power and ground cables for the internal 8-channel amp, and a USB link to a PC or iPhone for the tuning app.

Will the R2-S69 6x9" speakers integrate with an older factory head unit that lacks digital outputs?

Yes, the PXE-C80-88 includes anti-EQ for OEM systems and accepts analogue speaker-level signals, so the coaxial speakers work with legacy stereos.
