Great Amp
I had this amp connected in my now wife's car in the trunk in Texas Heat.. and it was a great product, never went into protect. Look guys, this is a front stage and rear fill unit.. not really meant for Subs.. of course it's gonna overheat like that.

Loud and Clear.
Got this thing hooked up nice to a pair of Component Alpine Type Xref's and a pair of Kenwood Execelon 172's. great clarity...hence Infinity. i only have it turned halfway up and its louder than any of my buddies systems. i can turn my head unit all the way up and its so clear and loud its disgusting. it makes everything sound perfect, and like your at the studio or concert. get it here. okay have fun get one right now cause this item is SICK.

Great Quality Reliable Amp!!!
This is the second Infinity 475a I've purchased and installed, the first was almost 7 years ago and hasn't given me any trouble and it's been in two different trucks I've owned. It's always been pushing Infinity Reference or Kappa Speakers and has done a great job. So I bought another one to install in my little brothers truck and hopefully I will get the same results!!! The amp gets a little hot to the touch but that was to be expected having no active cooling. But the amp has NEVER shut off on me!!! It's got great simple adjustments and the build quality seems solid. Would highly recommend, it's a great amp for the money!!!

a bit dissapointed...
I bought this amp hoping to use it to push to 12's. It is a great amp for mids and highs, but not much else. The description should make this very clear, and it doesn't.

Not Too Bad
Recently ordered this amp from Sonic. Shipping was fast and customer service was great. Finally got around to hooking it up and although I have not pushed it to hard as yet it sounds pretty good for an "entry level" amp. Signal to noise ratio isn't exactly the best as there is some hiss but so far it gives off pretty good power. Running it in tri way mode. Powering a set of components up front and a sub in the rear. Good enough for a daily system but not for a high sound quality build.

Sounds Excellent!!
I have this amp pushing 4 Infinity Kappa 682.9cf, in my little 2 door truck. It sounds so loud in a little truck!! Excellent high's and mids! I don't know anybody with a better system! Also, have 2 10inch JL W3 subs to balance it out.

Best in its class
$30 off list price isn't one of the better deals on Sonic, but I think this amp is currently being phased out, so get it while it lasts. And it's CEA certified, so you know you're getting exactly what's on the spec sheet. At 75 watts RMS, it's enough to amp your music as loud as your ears can tolerate, and then louder. It's fairly easy to use with an intuitive design, and is definitely one of the sexiest looking amps out there (and the blue lights look awesome).
The biggest downside is the 1% distortion. But if you're thinking about buying this amp, you're probably relatively new to car audio and would not be able to tell the difference between 1% and .1%
The two stars for durability is because my friend bought one and two of the channels blew. So he returned it for another, and one of the channels blew again. He ended up getting fed up and going with Alpine. But when I inspected his system before the alpine install, I noticed a shoddy ground connection. I'm guessing that is why he blew the amps. But I have never had a problem with mine. It overheated ONCE last summer, because it was mounted vertically, in direct sunlight, and being played for 90 minutes on high volume.
Bottom line: if you install it properly, you will have no problems, and will love this amp. As far as "entry level" amps go, 5 stars!

great product
I use this amp to power my four infinity speakers and one 300x1 infinity for a single sub and my car is loud and rockin, yet perfectly balanced.
