About the Infinity Reference 5760a
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 that you'll get the power as advertised.
Looking for an amplifier that's flexible enough to power the system you want? It's hard to go wrong with the Infinity Reference 5760a 6-channel amp. Four channels of 56 watts RMS drive all your full-range or component speakers, while two subwoofer channels (107 watts RMS x 2, or 287 watts x 1 in bridged mode) take care of your low-frequency needs. Grab hold of the optional wired remote and make level adjustments to the subwoofer channels right from your dash. This is one amp that you'll never outgrow.

Inputs and Outputs Notes
Status LEDs: The amplifier has the following status LEDs:
- Clip: indicates the amplifier is being overdriven, and your speakers may be in danger. This should blink only on musical peaks, and not be on constantly.
- Power: indicates the amplifier is on
- Protect: indicates any of the following problems: DC voltage on amplifier output, overheating, under voltage, over voltage, and short circuit in the speakers or wire
Variable Filters: The front, rear, and sub channels have separate filters. The front and rear channel filters can be set for low-pass, high-pass, or full-range operation. The sub channel filter is low-pass only. Each filter can be adjusted from 32 to 320 Hz. In each case, the filter has a slope of 12 dB per octave.
Bass Boost: For added low frequency performance, the sub channels have a 0 to 12 dB variable bass boost centered at 50 Hz.
Sub Channel Input: The sub channels have a mode switch that can be set to one of the following options:
- External Input: use this mode when sending a dedicated signal to the subwoofer inputs
- Internal Input: use this mode to send a signal from the front and rear inputs to the subwoofer; this is useful if your receiver does not have dedicated subwoofer outputs
Remote Level Control Compatible: The optional 100rc wired remote level control allows you to adjust the bass level from anywhere in the vehicle.
