Great amp
I've had this amp hooked up for 2 years now. Haven't had an issue with it yet. Seems like I can throw any speakers on it and it plays crystal clear.

Wonderful sound and noise free.
This amp has transformed my car system. The prior amp had an alternator whine that I could not resolve. A simple swap to this Sony amp and voila! No noise and a better tone. Sweet bass, clear midrange and sparkly highs.

Amazing Amplifier
This amplifier is definitely one of the highest quality sounding amps have ever heard especially at high volumes. The construction is just as good, the built-in fan is a big plus.
