Polk Audio is legendary for building some of the best speakers in the world. Now, they've extended their engineering expertise and dedication to great sound to their new Carbon series amps. These bruisers are designed to give your system two big advantages over the competition: massive power output and outstanding SQ. Plus, thanks to Polk's collaboration with Italian motorsports accessories designer MOMO, they've got a distinctive, stylish look.

The Polk/MOMO C400.4 is built to give you maximum installation flexibility. You can wire it in four-channel mode to power full-range speakers, or bridge it to stereo for 200 watts x 2. Polk's Maximum Dynamic Headroom power supply means that you get power on demand — your speakers won't falter, even during massive musical peaks.

If you're building an all-Polk system, check out this exclusive feature: the C400.4 features a Pre-EQ switch, which optimizes the crossover and bass boost for use with Polk/MOMO component speakers. It allows you to amplify the tweeters and midranges separately, applying the optimal equalization and crossovers, so you can eliminate the passive crossover networks that come with the speakers.

Everyone knows that great sound is paramount, and the C400.4 delivers. But in the world of car shows and competitions, looks matter, too. And how does the C400.4 look? In a word, excellent. Flexible three-way wire management lets you route your cables to the left, right, or bottom, and the cover plate conceals the controls and all your connections for an uncluttered look. Combine that with sweet carbon fiber accents and removable end caps (take 'em off to save space, or to mount two amps right next to each other), and you've got one stylin' power plant.
