Complete Audio Upgrade

This bundle combines an eight-channel digital sound processor amplifier with two shallow subwoofer enclosures, a pair of coaxial speakers and a pair of component speakers. It is built for car owners who want a full-system replacement without sourcing each part separately. The package delivers processing, amplification and speakers in one matched set.

Processor Power And Enclosure Design

The amplifier provides 50W x 6 plus 300W x 2 at two ohms and handles Hi-Res audio playback at 96kHz/32Bit through coaxial, USB and high-level inputs up to 30V. Each 12-inch subwoofer uses a neodymium magnet in a polymer enclosure measuring 22.25 by 5.25 by 13.125 inches and is rated for 300W RMS. Foam-padded brackets reduce vibration transfer to the vehicle.

Shallow-Mount Space Requirement

The subwoofer enclosures need only 5.25 inches of mounting depth, making them suitable for tight locations where standard boxes will not fit. Buyers with ample cargo space who prefer larger, deeper enclosures for maximum low-frequency output should consider other solutions.

Questions about this item

How is the Alpine PXE-C80-88 OPTIM8 amplifier installed in the vehicle?

The amplifier accepts up to 30V speaker-level input, Coax and USB connections; the step often missed is running the USB link to a PC or iOS device to run the auto sound-tuning routine after wiring.

What maintenance will the two SS-SB12 subwoofer enclosures need over time?

Check the foam-padded mounting brackets periodically for compression or loosening, and inspect the polymer enclosure for cracks; the 12-inch drivers and neodymium magnets are sealed and require no user service.

What is the first limit reached when the system plays at high output for long periods?

Each SS-SB12 enclosure is rated for 300W RMS power handling; sustained levels above that will hit thermal compression in the shallow-mount subwoofers before the amplifier reaches its 300W x 2 channel limit.
