Great Amp

CReed, Crutchfield
11 April 2012
  • Summary: THIS AMP ROCKS. 5 Channels, so I hooked a component set (6 1/2 door & Tweets) + Rear (Infinity 6 1/4) and the 5th channel I hooked a tear shaped box with 4 POLK 6x9 Woofers in it. All sounds exactly how I imagined...

Infinity 475a - a solid choice

Daniel, Crutchfield
11 April 2012
  • Summary: A very solid amplifier with good sound quality, and plenty of power. It pushes my polk db 6.5" component's and infinity 6x9's to their limits. I've had the 475a for 4 years now! This is the only amplifier I've had to not quit on me (mostly class D subwoofer amp's like the alpine mrp-350, mrp-1000; great amps, but gave out...). For me, the volume is at it's limit, or else I'm not listening to music haha.
  • Pros: great sound for the price
  • Cons: definitely runs hot - but who cares if it lasts?

INFINITY REFERENCE 475A

Mike T., Crutchfield
11 April 2012
  • Summary: I kept my stock head unit since it has an excellent tuner in it. One of my original speakers was blown. However adding this amplifier to a complete set of 4 6.5" Infinity reference component speakers has created fantastic sounds in my Avalanche. The Infinity speakers are rated to handle 90 rms peak and the unit puts out 75 rms so it's as perfect as you'll get. The clarity, as well as bass and highs is excellent. Thank you Crutchfield for a great price on a great product.

Runs HOT. Does not last long.

Anthony, Crutchfield
29 January 2012
  • Summary: Purchased this amp with the advice from a sales associate. It runs hot so have it in an open area. I was only able to get 2 1/2 years out of it tops before issues. It went into protect mode on and off. I called to see what it could be I was advised that its probably the speakers. So I purchased all new speakers. Wasn't the speakers it was the Amp.. I have an old Sony amp pushing my sub that's way over 15yrs old and it still works.
  • Pros: Produces good sharp sound
  • Cons: Can not depend on it working. Check reviews elsewhere. Lots of issues .

  • Summary: I recently purchased this amplifier to replace my kicker zx650·4. I expected a considerable decrease in sound quality. But I think this amplifier sounds just as good for half the price...very nice amp.
  • Pros: clean crisp sound
  • Cons: amp runs hot

Hot, Baby, Hot!!!!

  • Summary: Hot Baby Hot, IF you are out all night partying and driving and get hungry, then this amp is for you.Why you ask? Because this amp gets so hot you can cook eggs on it.I really can't say they all do this but i bought this one on ebay here off of someone and that may be the reason they were selling it.This thing runs for a while gets hot and goes into protect mode shuts off and then finally turns back on and before you know it back off it goes.

Infinity Reference 475a

Brian, Crutchfield
20 April 2010
  • Summary: 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!
  • Pros: Looks great and sounds even better
  • Cons: None so far
