The Mmats 6150D seems to be the an awesome amp for a one amp, relatively high output, 2 way and sub system. https://www.mmatsproaudio.com/site/product/hifi-6150d/
- 4 x 150 Watts RMS @ 4 ohms + 1000 Watts RMS @ 1 ohm
Plus, it's 10" x 9.5" X 2.25", so it's got a small foot print, too...
Most of us end up with multiple amps, so it's interesting to see this kind of performance in a single, small-ish package.
What is your perfect amp??
