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.

Sony won't honor warranty shipped in box XM-GS4
XMGS4 30 January 2020 by Disappointed27 (USA)
The Sony XM-GS4 shipped with a 3 year limited warranty (US and Canada). I purchased the amplifier on 10/29/2017 from an authorized retailer and tried to get a warranty repair for a dead channel on 1/30/2020. The customer representative insisted the warranty is only for 1 year and would not connect me to a manager to discuss the conflicting information, he just kept referring me to what his "system" says.

I had this installed in my Volvo wagon a month ago and suddenly I hear fingers on strings. An excellent choice to improve listening in a car.
