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 A150.4D 4-channel amp puts out 100 watts RMS per channel, plenty enough to satisfy most power-hungry speakers and music lovers. Audiofrog's onboard Flex Crossovers can be set as high-pass filters to clean up the sound for coaxial speakers and components sets, or as bandpass filters when you're actively powering tweeters and midrange drivers separately. You can also bridge this amp's ch...
