Our take on the Infinity Reference 1600a

Infinity's Reference Series amplifiers offer impressive power and extensive controls for fine-tuning your sound — an ideal way to boost your music's intensity and clarity. Strict reliability testing results in durable, dependable amplifiers, and their compact size gives you more installation options in tight places.

The Reference 1600a mono subwoofer amplifier ensures steady power delivery, thanks to its highly efficient, Class D design. This powerful amp will satisfy your inner bass head, delivering up to 600 watts RMS to your subwoofer system. And every Infinity Reference amplifier is certified to deliver power as advertised.

Adjust the amp's variable low-pass filter and bass boost to get more efficient output and cleaner low-end kick from your sub/enclosure combo. Preamp outputs simplify hookup to another amp in your system, so system building is quick and easy. Direct-connect terminals make reliable connections without any crimping or soldering.

Features

CEA-2006 Compliant: CEA-2006 is a new system of testing & measurement methods for mobile audio amplifiers. This voluntary standard advocates a uniform method for determining an amplifier's RMS power output and signal-to-noise ratio. The criteria for measuring power uses a DC input voltage of 14.4 volts and the RMS power output is measured into a 4-ohm load, with 1% or less Total Harmonic Distortion (THD) plus noise, and at a frequency range of 20 Hz to 200 Hz, when applicable. Signal-to-Noise ratio is measured in weighted absolute decibels (dBA) at a reference of 1 watt into 4 ohms. CEA-2006 allows consumers to compare car amplifiers and receivers on an equal basis. The Infinity Reference 1600a under CEA-2006 regulations is rated at 400 Watts RMS x 1 channel with a 80dBA signal to noise ratio.

Mono-Power Amp Design: The Infinity Reference 1600a is designed with specific features to power your subwoofers with a frequency range between 11-330 Hz. This amplifier is not designed to power a full-range speaker.

Class D Design: The Infinity Reference 1600a is equipped with a high-performance Class D switching power supply, which is more efficient than traditional class AB power supplies, and draws less current from your vehicle's charging system.

Protection Circuitry: The amp features 4-way protection, and will shut itself down in the following cases:

  • DC Output: DC voltage is detected on the amplifier output
  • Temperature: Amplifier is overheated
  • Over/Under Voltage: Voltage at the +12V (Battery) terminal is less than 8.5V or more than 16V
  • Short Circuit: Short circuit in speaker or speaker wire

Power and Protection LEDs: The amplifier features a Power and Protection LED on top of the unit. The Power LED illuminates Green when the amplifier is supplied power. The Protection LED will illuminate Red when the amplifier goes into protect-mode.

Controls

Input Level: Rotary control to match the level of the preamp input signal.

Low Pass Filter: The 1600a has a variable 12dB per octave, 32-320Hz low pass filter to prevent unwanted high-frequencies from reaching your subwoofers so they can play deeper and louder.

Bass Boost: The Bass Boost control allows you to enhance the bass output of your system at 50Hz up to 6dB.

Remote Level Control: The amp has an RJ-11 jack for use with the supplied remote sub-level control module. The amplifier also comes supplied with a 19.5' cable to connect the remote to the amplifier. This sub-level controller allows the subwoofer level to be adjusted from the listening position. The sub-level controller features a rotary knob and a power LED that illuminates green when the amplifier is powered on. The remote knob has integrated mounting flanges and comes supplied with two mounting screws to secure the remote unit to a flat surface of your vehicle. The wired sub-remote measures 2.205" wide x 0.698" tall x 2.025" deep.

Connections

Preamp Output: 1 pair of gold-plated RCA jacks (amp provides a non-filtered signal for daisy-chaining additional amplifiers).

Preamp Input: 1 pair of gold-plated RCA jacks.

Remote Level Control: RJ-11 jack for use with the supplied remote sub-level control.

IMS Input: This port is designed for future Infinity expansion products.

Speaker Output: 4 Set screw terminals for connecting speaker wires; handles up to 8 gauge (16 gauge minimum recommended).

Note: There are two sets of terminals to make it easier to connect multiple subwoofers. The terminals are connected internally in parallel.

Power:

  • +12V: Set screw terminal for power wire from battery; handles up to 4 gauge wire (8 gauge minimum recommended)
  • Remote: Set screw terminal for remote turn-on lead; handles up to 8 gauge wire (18 gauge minimum recommended)
  • Ground: Set screw terminal for ground; handles up to 4 gauge wire (8 gauge minimum recommended)

Fuses: 3 Slots for 25A fuses (installed).

Great Amp for Entry-Mid Level Subwoofers!!

Written By BrendanG, Middleboro, MA on Friday, February 18, 2011
 
This amplifier I use to power 2 300W JL Audio Subwoofers and let me tell you
this thing is impressive. Just watch out it draws a lot of power! Make sure you
have a capacitor or extra battery nearby if you plan on pushing this thing to peak.

With the internal fans, even after hours of being at or near RMS, this amplifier
does not cut out, get softer or anything.

To hookup, they give you two positive terminals to make a dual subwoofer setup
easy. Just note that behind the connector the two positive and two negatives are
connected. They are not separate channels.

Also the pre-amp outputs make chaining amplifiers together much simpler. I may
buy another, and not having to run more wires keeps me pleased.

For the price this is the amplifier for you!

Fantastic pushing boost on the subs

Written By Aaron, Butler on Friday, November 05, 2010
 
When you buy any subs to their max watts in-between the what the amps does equal amount of feedback from the subs handle in the circuit board sending a circuit holds the amps juice back from letting the sub work like it should to prevent the sub from blowing and over heating your amp

wicked good amp

Written By Jarvis, new paltz, ny on Thursday, February 04, 2010
 
i have to say i've had two mtx amps in the past and this amp just blows them away. i have it powering a kappa perfect 12vq sub and it does it easily. you can run it hard for a long time and it stays cool the entire time. the only thing about this amp that actually confused me is that it has outputs for two subs, like two channels, but the book they give you doesnt tell you how much each of them suppplies when both used. just what it can do in a mono hookup. o well, still an amazing amp!

Awesome Amp

Written By Dion, PA on Thursday, January 28, 2010
 
Recently bought this amp, and have it hooked up to a single Rockford Fostage Power
Stage 1 10'' sub (600 rms at 2 ohms.) Handles it with zero problem...after continuous
use, it barely gets warm. The blue light looks really cool too.

Great Amp

Written By Corey, Atlanta, GA on Sunday, May 17, 2009
 
This is a fantastic Amp. I have it running to two Rockford Fosgate Punch1 12's and it does the trick ! very easy install, and looks really cool when the blue lights up when power is supplied to it.
