Infinity Reference Series Amplifiers

Looking for a more moving audio experience? Take Infinity car audio for a ride. Innovative materials and breakthrough engineering have always put Infinity products out in front of the competition. So expect extreme output from Reference Series amps, but be prepared for accuracy and detail that may surprise you. There is no better way to make your car audio system stand up and deliver than by powering your speakers and subs with Infinity electronics.



All the right features to get the job done. Click to enlarge.

Infinity 1300a 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.

Style Name: 4-Channel/300 Watts Verified Purchase
I bought this amp to fit under the driver's seat of my 2000 CR-V. I had to cut the carpet and padding out from under the seat to clear the seat adjustment mechanisms, but it fits great and the glowing blue rails look pretty cool at night.

I've got this hooked up to an Alpine head unit via preamp-outs and driving two pair of Infinity 6020 6.5" Component speakers. I cannot describe the difference in sound from the old Infinity shallow-mount coax speakers powered by the head unit. The bass is so deep and powerful with no clipping or bottom-out. The highs are crystal clear and not overpowering. It's hard to tell how much was due to the new amp or the new speakers (since I made both changes at the same time) but I now find myself looking for excuses to drive my car just so I can listen to music. The amp has plenty of features (both low and high pass x-overs and 4x, 3x, and 2x bridging for a variety of sub/sat setups. It is pretty large, but quite attractive, and the sheer amount of clean power is incredible. Highly recommended for loud clean sound; I have not tried this with big subs.

Was NOT confident when I bought a pair of these amps to power one Infinity 12 each however this is one purchase you will NOT go back on! As always, the bass-remote feature lets you enjoy your music the way its meant to be no matter how loud you go.

Style Name: 4-Channel/300 Watts
I have owned this amp now for almost a month and I am very happy with it. it is powering two Kenwood 100watt rms 6x9's in the front doors and two infinity refrence 90watt rms 6.5's in the rear doors. My hu is a Clarion VZ409 and this amp compliments a great system with amazing sound. it has a set of preouts on the amp that allow you to link to another amp for a sub. i have it paired with a JL audio 250/1 slash v2 powering a 12W3V3-4 and i love the sound. the only problem i had was alternator whine which i fixed with a ground loop isolator. this is a great mid range amp with high end sound and features. i love it and reccomend it to all who want qualitry sound.

Style Name: 5-Channel/350 Watts
I bought this amp brand new less than a year ago and it has already died on me. My entire system was professionally installed and sounded great but for the price of the amp I certainly expected it to last much longer. I will be purchasing the Alpine PDX-5 as the replacement since there is no warranty. I loved the amp but would warn anyone due to it's short life span. The amp was installed in my pickup which is used on weekends, etc. and I never neglected my system like someone younger may have done. Buyer beware!

I have both this REF1300a amp and a REF1220se Sub/Enclosure and OMG! This amp with a single 12" Infinity 2 ohm sub is an AMAZING duo! You won't be disappointed with this amp. It also has 2 cool LED blue light bars on the face which make it look quite nice in a clean setup. Whether you are looking to rattle windows or enjoy a nice steady drumline, this will do it! Just my 2 cents...

Style Name: 4-Channel/300 Watts Verified Purchase
I've been using this amplifier for over six months now and have had absolutely no problems. I've been unable to raise the volume more than 3/4 because the sound level is simply just too deafening. I can play it at ear piercing levels with no discernible distortion. Hookup was easy and there are plenty of options to customize the signal for your vehicle and head unit. The manual is well written. I carefully selected this amplifier after much research and I have been highly satisfied with the results. It has exceeded my expectations. Do your own research and select the amp that best fits your needs. If you decide to purchase this particular amplifier do so with reasonable confidence that you will receive a quality product.

Style Name: Mono-Channel/300 Watts Verified Purchase
Easy install, worked on first startup, seems to work great with the infinity single voice coil 10" subwoofer I purchased. Sound doesn't distort. Only Downside is the size of the amp, but imagine that should lead to less heat issues. Happy with my purchase and would recommend as a good quality amp to power one sub. If you are looking to power two subs, I'd recommend the Infinity Reference 1600a 600-Watt, High-Performance Mono Subwoofer Amplifier (Silver/Black)

Also this amp only uses around 37amps max which according to the infinity website says you can use a 10awg wire, I went with an 8awg, but this is nice because for it's power it shouldn't place too much extra stress on your charging system.

Style Name: Mono-Channel/600 Watts
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!
