Our take on the Rockford Fosgate Punch 500.2

Rockford Fosgate

Plug Rockford Fosgate's Punch 500.2 amplifier into your car audio system, and you'll be thrilled by the sound. The combination of Rockford Fosgate's proprietary technology, clean circuit design, and MOSFET output stages brings more detail than ever before to your music.

Built-in crossovers let you sculpt your sound to work with your vehicle's acoustics. Punch Bass kicks in up to 18 dB of bass boost (at 45 Hz) to deliver a killer low end. If space in your vehicle is at a premium, you can remove the endcaps for a wider range of installation options.

Details:

  • 250 watts x 2 at 2 ohms
  • 500 watts x 1 in bridged mode
  • stereo, bridged mono or Tri-Way output
  • MOSFET power supply and output devices
  • 50-210 Hz high-pass/low-pass crossovers, 12 dB/octave slopes
  • 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 that eliminate 80% of ground loop noise
  • Trans•ana circuitry keeps preamp voltages low and signal paths simple for outstanding audio quality
  • NOMAD — advanced protection circuitry for "intelligent" shutdown protection
  • wired remote control included for fingertip control of Punch Bass (for 0-18 dB of bass boost at 45 Hz)
  • speaker-level inputs
  • dimensions: 13-7/16"W (9-15/16" without endcaps) x 2-7/16"H x 9-7/8"D
  • 3-year warranty

Features

TRANSana (TRANSconductance Active Nodal Amplifier): The TRANSana is a circuit that allows the audio signal to pass through the amplifier at low voltage. The signal is directly level-shifted to the fixed high voltage rails via a pair of drive transistors. Signal linearity is assured by an active node formed  by the drive transistors at ultrasonic frequencies. The result is crystal clear sound quality, even at high volume levels.

MEHSA (Maximum Efficiency Heat Sink Application): MEHSA is a Rockford Fosgate proprietary process that increases the heat transfer from the MOSFET devices to the heatsink. The multi-layer insulated metal MEHSA substrate operates with minimal thermal resistance, spreading heat both downward and outward to quickly dissipate heat from each device across the heatsink. This allows greater power output, enhanced thermal stability, and maximum reliability.

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.

NOMAD (NOn-Multiplying Advanced Decision): NOMAD is an intelligent protection circuit that uses an analog computer to make real time decisions regarding temperature, voltage, current and impedance. The unit is protected without limiting sound output unless needed.

Internal Crossover: The internal crossover is a 12dB/octave Butterworth filter variable from 50Hz to 210Hz. The crossover may be set for high-pass, full range, or low-pass operation.

Remote Punch Bass: The Punch Bass feature 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.

RF Center Badge: Upon arrival, the RF center badge is not adhered to the amplifier. For installation flexibility, the badge can be rotated 180 degrees. Once you've decided in which direction the badge looks best for your installation, the peel-and-stick backing on the badge can be used to attach it to the amplifier.

Controls

Left Side Of Amplifier:

  • Crossover Switch: Allows you to select high-pass, full range, or low-pass crossover operation
  • Crossover Frequency: The crossover frequency control is variable from 50Hz to 210Hz
  • Left Gain: This variable gain control allows you to adjust the output level of the left channel
  • Right Gain: This variable gain control allows you to adjust the output level of the right channel

Inputs and Outputs

Left Side Of Amplifier:

  • Input: Gold-plated RCA jacks
  • High Level Input: Molex plug input for included harness
  • Speaker Outputs: Gold-plated set screw terminals that will accept up to 8 gauge speaker wire
  • Remote Punch Bass: RJ-45 jack for use with supplied Remote Punch Bass wired remote

Right Side Of Amplifier:

  • GND (ground): Gold-plated set screw terminal that will accept up to 8 gauge ground wire
  • B+ (power): Gold-plated set screw terminal that will accept up to 8 gauge power wire

Specifications

Dynamic Power Rating (measured at 14.4V):

  • Bridged Into A 4-Ohm Load: 710 watts x 1
  • Per Channel Into A 2-Ohm Load: 330 watts x 2
  • Per Channel Into A 4-Ohm Load: 210 watts x 2

Continuous Power Rating (measured at 13.8V):

Manual Corrections

Bandwidth Specification: The manual incorrectly lists the amplifier bandwidth as 10Hz-200Hz (+0.3dB); the actual bandwidth is 10Hz-200kHz (+3dB).

Included Wrenches: The manual incorrectly states that this unit comes with 9/64" and 3/32" allen wrenches; 7/64" and 3/32" allen wrenches are included with this unit.
