Product Overview

The ground-breaking Alpine OPTIM™8 is the ultimate all-in-one solution designed to enhance and effortlessly fine-tune your sound system with remarkable precision.

Sounds great automatically

Alpine has eliminated the pain and confusion that usually goes along with trying to tune your system’s sound using a digital signal processor or DSP/amplifier by making an amplifier that tunes itself. The Alpine Optim8™ eight-channel PXE-C80-88 amplifier features automatic sound tuning and High-Definition performance so you’ll experience exceptional fidelity, clarity, balance, and impact in your music without having to spend hours fiddling with controls and testing devices.

Alpine’s DSP control app

Matrix mixing allows for summing and input/output signal management. Fully adjustable high-pass, low-pass, and bandpass filters, plus 31-band equalizers on every channel match the sound to your speakers and smooth out any hot spots or dips in the response due to your vehicle’s interior. The delay feature lets you center the stereo image for your listening position. After initial setup using your PC device, all adjustments can be made automatically using the PXE-C80-88’s control app run on your iPhone using its built-in mic, or with your PC using a separate measurement microphone, like Alpine’s KTX-CSP1. PC users can make all the sound adjustments manually to create a more personalized soundscape.

Power under the hood

While the PXE-C80-88 can act as a stand-alone processor for use with your own aftermarket amplifiers, its built-in 8-channel amp has plenty of power to run your system. It puts out six channels of 50 watts RMS each to speakers with 4- to 2-ohm impedances — so it’ll work equally well with factory and aftermarket speakers — plus two channels that can each produce 150 watts RMS at 4 ohms and 300 watts RMS at 2 ohms, to power louder mid-bass drivers and subwoofers.
