Infinity's Reference Series amplifiers offer impressive power and extensive controls for fine-tuning your sound — an ideal way to boost your music's intensity and clarity. Strict reliability testing results in durable, dependable amplifiers, and their compact size gives you more installation options in tight places.

The versatile Infinity Reference 5350a 5-channel amplifier sends 50 watts RMS to each of your front and rear speakers with its 4-channel main power section, while its mono subwoofer channel delivers up to 300 watts to your subwoofers. And every Infinity Reference amplifier is certified to deliver power as advertised.

The sub channel can receive its signal directly from your car stereo's subwoofer preamp outputs or as a sum of the amp's front and rear input signals. You can operate this amp in 3-, 4-, or 5-channel modes, so this is one amp that you'll never outgrow.

The variable frequency filters and adjustable bass boost let you contour the amp's output to suit your speakers and subs for more efficient output and cleaner low-end kick. Preamp outputs simplify hookup to another amp in your system, so system building is quick and easy. Direct-connect terminals make reliable connections without any crimping or soldering.
