Description Features Crutchfield Hands-on Research Accessories
 

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 heavy-hitting Infinity Reference 475a 4-channel amplifier sends 75 watts RMS to each of your front and rear speakers. Or, you can bridge the amp to 2-channel mode, and pump out 360 watts total to your two subs. And every Infinity Reference amplifier is certified to deliver power as advertised.

The variable frequency filters and adjustable bass boost let you contour the amp's output to suit your speakers or subs for more efficient output and cleaner low-end kick. Preamp outputs simplify hookup to another amp in your system, so system building is quick and easy. Direct-connect terminals make reliable connections without need for any crimping or soldering.

January-29-12
Reviewer: Brian from Terre Haute IN  
I purchased this for my son's 96 Ford Contour with 4 6x8 Kenwood  speakers in the doors. We had previously installed a Kenwood headunit and b4 the amp it sounded pretty good. After installation I was absolutely blown away! I couldn't have imagined how good this  small system was going to sound. Highs are clear and loud and the bass is difficult to believe unless you hear it firsthand. My 17 yr old son decided to not install a sub! It's only been running 3 weeks but no problems  whatsoever and astounding performance.


 
Good sound, bad quality April-20-10
Reviewer: rnd from Boston, MA  
I had this mounted in the trunk with lots of open space around it for a cool air supply.  Never abused, this amp lasted 7 months when the front right channel went out (same as another reviewer here...).  It performed well up until then.  I have always thought Infinity's products were very good for their price point.  This one was a disappointment.  

Will it last?  It's a gamble.

Best customer service on difficult sale August-19-09
Reviewer: Rix from Charlottesville, VA  
The quality of customer service is not measured during the smooth sales nearly as much as it is with the difficult sales.  I bought this amp from Norm, who had sold me other equip. I was going to get Crutchfield to install. Upon review by the installer, Devon, he found that he was going to have to do some extensive electrical surgery that was not in Crutchfield's database. I appreciated explanation, and return of the amp was cheerfully accommodated. I was impressed with the trouble Norm & Devon went to try to figure an easy way to make the install work, but, in the end, it wasn't worth the tradeoffs I would have had to make. Thanks, guys, and I will definitely buy from you again!


 
Clear and powerful April-28-09
Reviewer: Anthony from Chicago, IL  
Just got say this amp is awesome. It's powers my 6.5" component polk audio dbs very clearly. I can turn it up real loud without distortion. This is my first amp i bought. Never thought my car would sound so much clearer and that loud.

Pros: Dirt cheap 75wx4 at 4 ohms. I probably can turn it all the way, but don't want to blow out my ears. Also its alot smaller than my sub amp. it's heavy, but looks nice and built to last.

Cons: People say it gets hot, it does, but it never shuts down on me. I don't know, but i had to switch around the patch cables a little. I dont know which one was that fault the radio or amp. No biggie Crutchfield helped me out.

I would reccomend it to my friends and family.

Also I want to say to Crutchfield. Thank you for helping me out with my purchase. You guys are the best.
