LIL BRO's

The heavy-hitting Infinity Reference 7451a 4-channel amp is more than ready to take on your mobile audio needs whether it's powering top-end component speakers, or supplying the juice to get two subs rocking! If you're powering components, the 7451a offers four channels of 111 watts RMS power, ready to make the highs sing and the lows pound. Variable high- and low-pass filters (32-320 Hz, 12 dB/octave) allow you to trim the range of frequencies being amplified so you can maximize speaker performance. If you're running a pair of subs, the 7451a pumps out 278 watts by two channels in bridged mode. That's more than enough to create your own temple of boom with all but the most power-hungry subs! The MOSFET power supply ensures your subs won't ever be starved for power, and there's also a bass boost (0-12 dB at 50 Hz) for when you need that extra kick. The 7451a will integrate smoothly into your system, thanks to preamp- and speaker-level inputs, as well as full-range preamp outputs.
