Infinity 5350a 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.

This review is from: Infinity Reference 5350a High Performance 5-Channel Amplifier (Silver/Black) (Electronics)

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 couldnt be happier with this amp.Im running 4 infinity 6 3/4 speakers and and infinity 12 inch boxed sub in my trunk.2 of the 6 3/4 in the front doors and two on the rear deck of my toyota corolla.I had to add 2 ground loop isolators to get rid of the whining sound from the alternator also.Im using a kenwood cd player in the dash that is made for the car.Sounds outstanding.I paid less than 1000 dollars for the whole setup which isnt bad for a decent car stereo.

This review is from: Infinity Reference 5350a High Performance 5-Channel Amplifier (Silver/Black) (Electronics)

I was worried after purchasing the amp because I read a poor review. Knowing that my daughter wanted a hard-hitting sub, I was worried. However, after listening to her stereo my fears were unwarranted. The stereo sounds great and my daughter is very happy with her system.
