Infinity Reference 7005A 5-Channel Amplifier

Streamlined for power

Looking for power for your entire system? Infinity's sleek Reference 7005A five-channel amplifier will add firepower and excitement to your music without losing its cool. This power plant will pump out 50 watts RMS to each of your front and rear speakers, plus up to 500 watts RMS to a sub. For a high-performance system, you can bridge the amp to 3-channel mode to power front speakers with 150 watts RMS each, while still driving the sub with 500 watts. The sub channel's Class D design ensures that its high output will put minimal strain your vehicle's electrical system.

Works in almost any vehicle

Speaker-level inputs and signal-sensing turn-on allow this amplifier to work in almost any system, even if you're keeping your car's factory radio. Wiring adapters are included with the amp for just that application. Separate high- and low-pass filters on the front and rear channels maximize your speaker system's performance. The subwoofer channel features a low-pass filter, bass boost, and phase switch, so you can make the bass sound great in your vehicle. A wired remote lets you control the bass from your front seat.
