Infinity Reference 7540a 111W x 4 car amplifier

Whether you're building a component system, powering a pair of full-range speakers, or just pounding away with a subwoofer, there's an Infinity Reference series amp ready to take on the job. Boasting impressive power ratings and fine-tuned controls, these amplifiers are capable of sending your music to new sonic heights.

It's all thanks to high-output MOSFET power supplies — which ensure maximum power delivery to your speakers for efficient operation — and variable filters that let you contour the output to fit your music. And, since every Infinity Reference amplifier is CEA-2006 compliant, you'll know you'll get the power as advertised.

Whatever your power needs, the versatile Infinity Reference 7540a multi-channel amplifier can take care of them. With 111 watts RMS x 4 channels, it can easily drive two sets of full-range or component speakers. Or, you can bridge the channels to stereo mode, and send 278 watts RMS each to a pair of subwoofers or component speaker system.
