Infinity's Reference 7005A 5-channel amplifier provides a full system solutions without breaking a sweat, and it'll look good doing it. It delivers 50-Watts RMS to each of the front and rear speakers, and a ground pounding 500-Watts RMS to the subwoofer channel — a much better balance of "speaker-to-sub" power than most of conventional 5-channel amplifiers on the market. For higher output, you can bridge the amp to 3-channel mode and power your front speakers with 140-Watts per channel, while still delivering 500-Watts to the subwoofer channel. Speaker-level inputs allow the Reference 7005A to work in almost any system, even if you're keeping your factory radio. Separate high-pass and low-pass crossovers on the front and rear channels and dedicated low-pass crossover, bass boost, and phase switch for the subwoofer channel provides an incredible amount of control and tuning capability. The Reference 7005A is truly a total system solution in one easy to install chassis
