Description

Rockford Fosgate Power T1500-1BDCP

The T1500‑1BDCP is a mono subwoofer amplifier engineered for serious bass performance. It delivers 1,500 watts RMS output stable down to 1-ohm loads, thanks to its Class‑BD topology and Constant Power design. With features like MOSFET power & output stages, dynamic thermal management, and adjustable filters & bass boost, it gives both sound quality and brute force for demo-level SPL builds or high-demand subwoofer systems.

Questions and Answers

Q1: What impedance loads is the T1500‑1BDCP stable at?
It is stable at 1Ω, 2Ω, and 4Ω, delivering full RMS power of 1,500W at 1Ω & 2Ω, and ~1,000W at 4Ω.
Q2: What does “Constant Power” mean, and how does it help?
Constant Power design ensures the amplifier delivers ~25% more power under real‑world load changes, improving consistency and performance across different impedances.
Q3: Are there built‑in filters and controls?
Yes — it includes a Low‑Pass crossover (35‑250Hz @ 24dB/octave), infrasonic filter (fixed at ~28Hz @ 12 dB/octave), and a Bass Boost control (0‑18 dB at 45Hz).
Q4: Does it come with remote bass control?
An optional wired remote Punch Bass EQ is available (sold separately) to override built‑in bass settings.
Q5: What are the wiring and power requirements to maximize performance?
Use 4 AWG power/ground wires, a beefy 200A fuse inline, and ensure the car’s electrical system (alternator, battery) can support high current draw.
