Loud and Clear.

The following review is for 475a, which is a part of the bundle you are viewing.

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.

Not Too Bad

The following review is for 475a, which is a part of the bundle you are viewing.

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.

a bit dissapointed...

The following review is for 475a, which is a part of the bundle you are viewing.

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.

Best in its class

The following review is for 475a, which is a part of the bundle you are viewing.

$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!

Excellent Quality

The following review is for 09ZCK84, which is a part of the bundle you are viewing.

I'm using this wiring to power my 4 channel amp in a full size crew cab truck. There is plenty of wire to run all the way from the head unit around the door sills to under the back seat. Very impressed with the quality of the cables and Sonic's delivery and prices.
