Overview

Our take on the Kenwood KAC-748

Kenwood's KAC-748 4-channel amp features variable high-pass and low-pass crossovers (50-200 Hz), front and rear. You'll get the best possible sound from your system by sending just the right frequencies to each speaker. And you'll have multiple hookup options. Drive 2 pairs of stereo speakers, or bridge the 2 rear channels to power your subwoofer, and use the 2 front channels for your main stereo pair.

This 4-channel Kenwood is built with MOSFET-switching power supplies for fast response, maximum output, and cooler operating temperatures. Larger-than-usual noise-suppression filters make sure that all you hear is music. Speaker-level inputs allow easy connection to any head unit.
