Based on customer reviewsRockford Fosgate Power 500W — clean, hard‑hitting bass for serious subs
This Power 500 Watt Class‑bd Constant Power Amplifier delivers very high, tight and clear low end while running cool and reliably; ideal for listeners who want powerful, low‑distortion bass but requires proper gain setup and robust speaker/sub matching.
What buyers praise
- Very high output—drives large subs and produces strong, physical bass
- Clean, tight bass with low distortion even at high levels
What to watch for
- Extremely powerful—can be overkill for casual setups or small subs
Overview
A 500-watt mono Class-BD amplifier tuned specifically for subwoofers. The proprietary Constant Power configuration increases usable output across impedance loads and the frequency response is optimized for bass.
Best for
- Dedicated car subwoofer systems
- Compact or under‑seat subwoofer installations
- Applications requiring a mono amplifier optimized for low-frequency reproduction
Key points
- 500 Watt mono output (Class-BD)
- Constant Power design — up to 25% more power across impedance loads
- Frequency response optimized exclusively for subwoofers
- Balanced Differential Inputs for reduced noise
- Punch Bass EQ and DSM
- CTA-2006 compliant
Fit and use
Intended as a dedicated subwoofer amplifier. The design supports use in compact locations (including under‑seat) and can drive multiple subwoofers — for example, it can be used to power two 4-Ohm DVC subwoofers. It is not optimized for full-range speakers.
What to know
Designed exclusively for subwoofers; not intended as a full-range amplifier. Constant Power configuration delivers increased output consistency across different impedance loads. CTA-2006 compliance indicates measured performance under standardized conditions. Balanced differential inputs help minimize system noise; co…

Manufacturer details
The Power T500-1bdCP is a 500 Watt mono amplifier featuring Constant Power delivering up to 25% more power across all impedance loads. The frequency response of the T500-1bdCP is optimized exclusively for use with subwoofers.
Additional details
The T500-1bdCP is based on the legendary T500-1bd amplifier design with a proprietary "Constant Power" configuration delivering up to 25% more power (Watts) across all impedance loads. The listening experience is cleaner, louder and more impressive than ever before. With the T500-1bdCP, you can now use an "under-the-seat" dedicated subwoofer amplifier to drive two 4-Ohm DVC subwoofers. This amp will provide enough bass to separate you from those envious car audio geeks.
