Here's an amp that's got only one thing on its mind — bass. Rockford Fosgate built the Power 1000bd to produce up to 1000 watts (into 2 ohms) of reality-warping, life-changing power! Designed with Rockford Fosgate's patented Class bd technology, this compact unit weighs in with an amazing 75% efficiency rating — that means you get less heat and more pure power. Even under stressful loads, it will stay cool and maintain rock-solid power flow, minimizing distortion.

The variable low-pass crossover (50-250 Hz at 24 dB per octave) allows you to adjust the bass for your vehicle's acoustics. The wired remote gives you front seat control of your bass impact, with up to 18 dB of Punch Bass at 45 Hz.

The unregulated power supply and 2-ohm compatibility put awesome power at your command. Hook up a single 4-ohm sub for 500 watts, a pair of 4-ohm woofers for 1000 watts, or (how's this sound?) four 8-ohm speakers jamming on 1000 watts — the possibilities are endless. And, though this amp takes up much less space than most high-powered amps, you can take off the end caps for an even smaller installation profile.

  • Class bd technology
  • 500 watts RMS x 1 at 4 ohms
  • 1000 watts RMS x 1 at 2 ohms
  • requires 4-gauge power and ground leads — wiring and hardware not included with amplifier
  • 4-gauge power and ground connectors
  • 100-amp fuse and fuse holder required (not included)
  • selectable 50-250 Hz variable low-pass crossover, 24 dB/octave
  • MEHSA mounting technology increases the heat transfer from the MOSFET output devices to the heat sink, for higher power output, lower operating temperatures, and greater reliability.
  • TOPAZ noise-killing differential inputs eliminate 80% of ground loop noise between the head unit and the amp.
  • NOMAD advanced protection circuitry monitors temperature, voltage, current and impedance, and provides "intelligent" shut-down protection without limiting system performance.
  • preamp outputs for easy connection to a second amplifier
  • wired remote control of Punch Bass (0-18 dB centered at 45 Hz) — gives you fingertip control of your bass impact
  • POWERsync — a 6-pin mini-DIN connector that allows you to bridge together two separate Rockford Fosgate Class bd amps
  • subsonic filter removes frequencies below the range of human hearing for increased efficiency
  • dimensions: 14-7/16"W (10-7/8" without endcaps) x 2-7/16"H x 9-7/8"D

Inputs and Outputs
Wiring Recommendations


STARDUST Class BD Design (Single-Terminal Alternating Rail DUal Sampling Topology): STARDUST Class bd design offers high efficiency with a very stable output.

Cast Aluminum Heatsink: The cast aluminum heatsink dissipates heat generated by the amplifier's circuitry. The inherent advantage of casting provides a 30% improvement of cooling over conventional extrusion heatsink designs.

TOPAZ (Tracking Operation Pre-Amplifier Zone): TOPAZ is a circuit that simply eliminates noise. The TOPAZ circuit allows the amplifier ground to move with the source unit ground, creating a "noise elimination" zone just before the preamp section. If there is any noise in the ground coming down the RCA line to the amplifier, TOPAZ amazingly tracks it down and eliminates it. The result is a 30-40dB improvement of the isolation between input ground and chassis ground. 

DSM (Discrete Surface Mount): In the manufacturing process high speed robotics are used to place 0% tolerance resistors and large board traces providing greater reliability and efficiency.

Internal Crossover: The internal low-pass crossover is a 24dB/octave Butterworth filter with a crossover point variable from 50Hz to 250Hz.

Subsonic Filter: A high-pass filter designed to prevent frequencies below the audio range from being applied to the subwoofer from the amplifier. Consequently, improving subwoofer performance and power handling.

POWERsync: This feature allows this amplifier's power to be joined with the power of another Class bd amplifier using a bd Sync cable (not supplied). Once joined together, you can power a single woofer using both amplifiers.

Remote Punch Bass: The Punch Bass helps correct for acoustical deficiencies in the listening environment by helping reproduce full range sound without adding excessive boost. The Punch Bass control has a narrow band adjustment centered at 45Hz, variable from 0dB to +18dB. Using the mounting bracket, the supplied Punch Bass wired remote can be mounted in any convenient location under your vehicle's dash. The wired remote is 2.317" wide, 1.523" tall and 2.035" deep.

RCA Pass-Thru Jacks: The pass-thru jacks provide a convenient source for daisy-chaining an additional amplifier without running an extra set of RCA cables from the front of the vehicle to the amplifier location. The pass-thru jacks output a full signal.

RF Center Badge: For installation flexibility, the RF center badge can be rotated 180 degrees. The LED power indicator is located under this badge and is visible through it when power is applied to the amp.

Wiring Recommendations

Wiring Recommendations: This amplifier requires 100-amp fuse protection, so its fuse rating exceeds that of typical 4 gauge wiring kits, which tend to include a 60-amp fuse. To protect the amplifier and power cable, we recommend placing a 100 amp fuse and fuse holder near the battery and another fuse and fuse holder near the amplifier. For 100-amp fuse protection, an ANL wafer style fuse is required, but none of the 4-gauge wiring kits include a ANL-style fuse holder. Since pre-packaged amplifier wiring kits cannot be used alone, you may purchase all the necessary items separately, or you may use a pre-packaged 4 gauge wiring kit along with two ANL-style fuse holders and two 100-amp ANL wafer fuses. If you do not use a wiring kit with the necessary additional items, the separate parts and wiring needed to install this amplifier are as follows:

  • 2 ANL wafer-style fuse holders capable of accepting 4 gauge wire
  • Two 100-amp ANL wafer fuses
  • 2 power rings for 4 gauge cable
  • 4 gauge power cable (to connect the battery to a fuse holder and the fuse holder to the amplifier)
  • 4 gauge ground cable 
  • Remote turn-on cable (speaker wire can be used as remote turn-on cable)
  • 1 stereo RCA patch cables
  • Speaker wire
