Infinity 1600a Features

Class D Subwoofer Amps
Efficiency is the benefit of the Infinity Reference Series Class D subwoofer amplifiers. A higher percentage of the power the amp extracts from the car's charging system is converted into output to the speakers, and less is wasted as heat. That is really important if you're trying to provide power to a 1000-watt amplifier. Class D technology turns the analog input signal into a series of pulses that can be amplified more efficiently by transistors used as switches, rather than valves. They're either on and operating at their most efficient level, or they're off. The pulses are converted back into an analog signal by an output filter.

CEA-2006-Compliant
All Infinity amplifiers are tested in accordance with CEA-2006, which provides a testing procedure to help customers compare amplifiers accurately--apples to apples. Specs are based on industry-accepted standards, rather than on the whims of amplifier companies' marketing departments. Look for the CEA-2006 logo when comparing amplifiers, to be sure you're getting the power you're paying for.

Audiophile-Quality Full-Range Amplifiers
Class AB full-range amplifiers offer audiophile quality performance and the best compromise between efficiency, low distortion, maximum available headroom and output power.

Amps That Don't Break
Infinity amplifiers are tested according to the strictest and most demanding reliability-testing regimen ever designed for car audio amplifiers. They are shaken, baked, frozen, dropped and shocked--all while they're operating. When they've passed all these tests, they are tested again. The result is a series of amplifiers that just don't break.

DBO Bass-Optimization Circuit
provides superior control and adjustability, compared to traditional bass-boost. DBO is a 2nd order high-pass filter that can be adjusted between 20Hz and 80Hz. The boost (or Q) adjustment boosts the signal above the highpass filter frequency. Used with a sealed box, it can help to increase output for more "fun" if it's set to about 45Hz. If it's used with a vented box, it should be set at or slightly below the tuned frequency of the box. That will prevent woofer unloading, and provide more output at the frequency where the box is tuned and the woofer's excursion is minimized--where it can handle more power.

Onboard Electronic Crossovers
Reference Series amplifiers include 2nd order (12dB/octave) slopes and are continuously variable from 32Hz to 200Hz.

Variable Bass-Boost
Provides up to 12dB of boost at 50Hz in the Reference Series full-range amplifiers.

Direct-Connect Terminals
Eliminate the need for additional solder-on or crimp-on terminals and provide an easy and reliable connection for power, ground and speaker wires.

Full-Range Preamp Outputs
Eliminates the need for signal splitters.

5.0 out of 5 stars Great Amp, powering my Infinity sub., February 23, 2011

A Kid's Review

This review is from: Infinity Reference 1600a 600-Watt, High-Performance Mono Subwoofer Amplifier (Silver/Black) (Electronics)

I just finished setting up my sub and I am very impressed. This was my first time ordering parts for a vehicle sound system.
I have this amp powering an Infinity Reference 1262w 12-Inch subwoofer, which is in a Scosche SE12CC 12-Inch Enclosure. I wired the DVC as a series, and it sounds amazing!
I installed the sub and amp into the trunk of a 2009 Ford Taurus SEL which still has it's stock "audiophile" 4 speaker setup. I'll soon be replacing these with four Infinity Kappa 682.9cf speakers!

I had an audio shop install the wiring for the amp and I connected it myself once I received the amp. Everything went very smoothly, and the connectors appear to be very high quality.
Since I listen to mostly Classic Rock I generally don't like to blast loud bass, so I have the sub turned down quite a bit. Even so, I still get that good "punchy" sound when I need it.

OVERALL: First time setting up a sound system; good, solid, and easy to make connections; powers a 12-in DVC Sub wired as a series (8-ohms) easily, no issues here!

This review is from: Infinity Reference 1600a 600-Watt, High-Performance Mono Subwoofer Amplifier (Silver/Black) (Electronics)

Not much to say, It's a great sub amp and easily handles a 2ohm load. Has the standard features, adjustable gain, adjustable crossover, and even comes with a wired volume remote if you wish to install it. It looks great and is solid as a rock. blue LED bands are a nice touch too.
