Rockford Fosgate Power T750X1bd
$550.00
Compact mono subwoofer amplifier — 750 watts RMS x 1 at 1 to 2 ohms
The Rockford Fosgate Power T750X1bd is a high-performance mono amplifier designed specifically for subwoofer applications, delivering impressive power from an ultra-compact chassis. This versatile amplifier can provide up to 750 watts RMS into a 1-ohm load, making it capable of powering multiple subwoofers for deep, powerful bass.
Despite its compact size (just 8-1/2″ × 4-5/16″), this amplifier incorporates Rockford Fosgate’s proprietary Class BD technology, which offers significantly higher efficiency than typical Class AB amplifiers (75-80% vs 20-60%) while maintaining lower distortion than standard Class D designs. This means more of your vehicle’s electrical power is converted to audio output rather than wasted as heat.
The T750X1bd features Rockford’s Constant Power technology, which actively monitors subwoofer performance and increases internal voltage and current when impedance rises. This results in up to 25% more total power output, particularly in the crucial sub-bass frequencies below 50 Hz where impact and authority matter most. A dual-fan forced induction cooling system prevents overheating, enabling sustained high-output performance even during demanding bass passages.
