Autotest 1500 (The Original Crest Pro Audio 8001) Power Amplifier Tested Working 8 ohms 720W 4 ohms 1200W 2 ohms 1400W Bridged 8 ohms 2250 Bridged 4 ohms 2800 Has double the amount of filter storage capacity than the crest 8001 version Original High-Capacity Filtering Enhances Bass Stiffer Power Supply: Increasing capacitance results in a "stiffer" power supply, allowing the amplifier to hold voltage steadier when it draws more current for heavy bass, resulting in tighter, more controlled low-end. Instant Energy Release: capacitors can discharge energy almost instantly. A 140,000 µF capacity is significant and acts as a "spring" or buffer, releasing power to the subwoofer instantly on high-demand, low-frequency notes. Reduced Distortion: By preventing the amplifier from struggling for power, the capacitor reduces distortion on deep, demanding bass, allowing the subwoofers to play cleaner and harder.
