Audiofrog

Audiofrog built this amplifier using high-tech component applications and circuit design, so you get high power and high fidelity performance from a small rugged amp that'll fit almost anywhere in your car. The Class D power-switching, modulation, and error correction circuitry all use high-frequency control signaling. That allows smaller-than-usual electronic components to safely handle the signal — and lets Audiofrog create such a powerful amp that's so small. A 4-layer circuit board and a dual-purpose heat sink shield both help eliminate noisy electromagnetic interference. Differential inputs also help keep out noise. The A600.1D mono subwoofer amp puts out up to 600 watts RMS, plenty enough to satisfy most power-hungry subs and bass lovers. Adjustable onboard controls include a subsonic filter to reign in resonance and low-frequency noise, a low-pass filter that'll clean up the sound for mid-bass drivers as well as subwoofers, a bass boost to emphasize the low end, and a phase adjustment to integrate t...
