Ground Zero GZIA 1500.1 1ch クラスD アンプ 1530W

Soldered in the subs last weekend and this thing stays ice cold even after an hour of hard bumping. Class D efficiency is real, that 1-ohm stability means I can push it all day without worrying about thermal shutdown. Bass hits clean and controlled, exactly what my setup needed.

Running this at 1 ohm and it hasn't broken a sweat yet — the bass hits way harder and cleaner than the price suggests. Class D means it barely warms up even after an hour of pounding subs.

Swapped my old amp out for this class D and the difference in tightness is immediate — my sub finally hits clean without that muddy flab on low notes. Runs cool too, even after an hour of pushing it hard.
