Overview
Infinity's Reference 4555a 5-channel amplifier will add a lot of muscle to your music without breaking a sweat, and it'll look good doing it. This amp sends 45 watts RMS to each of the front and rear speakers in your car while delivering up to 500 watts RMS to a subwoofer - a much better balance of "speaker-to-sub" power than most 5-channel amps provide. For a high-performance system, you can bridge the amp to 3-channel mode to power your front speakers with 130 watts RMS each, while still driving the sub with 500 watts.
