Alpine PXE-C80-88 OPTIM8 8-Channel Amplifier, SS-SB12 Subwoofer, R2-S652 & R2-S69 Bundle

Complete Audio Upgrade

This bundle delivers a full car-audio overhaul in one package. It combines an 8-channel digital sound processor amplifier, a shallow 12-inch preloaded subwoofer enclosure, 6x9-inch coaxial speakers and 6.5-inch component speakers. The system suits drivers who want concert-level clarity without fabricating custom enclosures.

Sustained Output Stability

The processor’s built-in amplifier runs eight channels continuously while the 31-band parametric and graphic EQ maintains tonal balance during long listening sessions. Automatic sound tuning via PC or iPhone app adjusts crossover points and time alignment in real time, preventing thermal compression that can dull dynamics after the first few tracks. The subwoofer’s front-mounted neodymium motor and dual voice coil dissipate heat efficiently, so bass stays tight even at extended high volumes.

Factory System Replacement

This kit replaces a typical head-unit-plus-factory-speakers setup where limited power and fixed EQ restrict detail. The jump is worthwhile when the vehicle lacks pre-amp outputs or space for a deep subwoofer box, because the 5.25-inch enclosure depth fits behind most rear seats. Buyers who need more than eight amplified channels or a larger cone area for SPL competition should look elsewhere.
