Make your multi-speaker system sound spectacular

Alpine's PXE-X121-12EV amplifier and digital processor is a versatile upgrade that'll deliver high-fidelity sound to almost any car audio system, aftermarket or factory. The amp features 12 channels with staggered output power and DSP control to accommodate multi-speaker systems found in many newer vehicles that have a mix of tweeters, small and large midrange drivers, full-range speakers, and subwoofers. For example, this amp can drive four dash-mounted tweeters and small speakers with 25 watts each, six front and rear door component systems and speakers with 50 watts each, and a subwoofer with up to 200 watts from bridged channels 11 and 12.

DSP control via Bluetooth® app

You can control the PXE-X121-12EV's digital processing wirelessly with your iOS or Android device or wired to a Windows PC via the supplied Bluetooth adapter and USB cable. With the app, you can stream music as well as control the amp without needing a receiver. You download the free Alpine Music App for iOS or Android device from the Apple APP or Google Play Store. The PXE-X121-12EV Pc app for Windows is available from Alpine.

Mixing, matching, and stereo placement

Matrix mixing allows for the summing and management of all the input and output signals. Fully adjustable high-pass, low-pass, and bandpass filters on every channel match the sound to your speakers. 31-band equalizers help achieve the perfect tone, allowing you to smooth out any hot spots or dips in the frequency response of your vehicle's interior. The delay feature lets you center the stereo image for your listening position.
