Nice little high quality amp. I use it to drive 4 high frequency speakers in my car. Sony used high quality wires on the set of connectors that came with the amplifier. I was surprised to see a thick conductor under a thin layer of the isolation, usually it's the other way around.
High quality amp Really low noise Does rated 4x45W - it's CEA-2006 certified. High efficiency digital design
Doesn't have sensitivity adjustments; but If you use it with a DSP or an active crossover it doesn't matter
