    Jp33 amp

    Posted by Dwill on Mar 14, 2024

    I will say the amp pounds and sound quality is better than I expected. I only gave it 4 stars only because I ordered the black one and got the green but I still used it anyway. I know if I called they would have made it right .

    A monster that runs cold at 4ohm and never sweats

    Posted by Adair audio solutions on Nov 10, 2023

    Super impressed with this amp and finally found my mono I been looking for. I tried Mmats m1400 and skar skv2 and stereo integrity 1500 and finally landed on the one. Only annoying thing is manually turning on the bass knob.
