Neatly Fits My Customization For The Trunk

Delivers enough power to satisfy a hungry thought. I have this running to my 2 front speakers and my subwoofer in the trunk. Makes the sound a lot cleaner than with speaker wire hooked directly to the cd player. Tends to overheat if you play 6/7 of volume and goes into protection mode for a short time. Be careful if that happens.

Nice Amp

I had this amp installed in my 2010 outlander along with new Polk Dxi 650 series speakers. Stock head unit. This is a powerful amp for the price. The only issue I have is with the instructions on the setting which are poor at best. But after some tweeking I am vey pleased.
The other thing is the width of the amp, it needs plenty of room.

awesome and surprising!

I have this wired to two Alpine Type R's in a custom fiberglass enclosure tuned to 34hz and I have 2 guage wire running to it and an optima battery. (2006 ford explorer) this was bought to cost effectivly replace my 3000 watt lanzar 2 channel. man this thing thumps the subs just as hard as the Lanzar for the same money and 1/4 the power. I recommend to anyone. this is reliable and strong. Great product Sony!

Great bang for the price

Powering 4 Rockford fosgate 3 way in 2008 Chevy crew cab . Good bass response & crystal clear sound due to the low THD%

Great amp for the money

I have this amp pushing 2-6.5" (w/ tweeters). 1-6x9" and an 8" sub. Sounds great and it defintely pushes some db's. There are settings on the amp itself you can use to boost your sound with which is a nice benifit. I've had this for about 8 months and I haven't had any issues with it. I will be buying another one for my new car soon.

Great service and value

This product does its job very well. It shows to be good heavy duty quality that you would expect form Sony. The only negative point would be its size because of mounting location. I would recommend this product and I would buy it again.
