I own the first 2 amplifies 2 JB systems Vibe 12 (sound reinforcement) and the second (in bridge mode) amplifies a sub JB Systems Vibe 15 Mk2. The robust design of the chassis, the presence of a transformer and here we are with a beast of 16Kg, which sends power without complaint and with clarity TRUE. Even after long-term concerts, not to mention abnormally warm. Recommended!
