Our Product Research Team
At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere.
That's because we have our own in-house Product Research team — they open the box,
verify contents, check the owner's manual, and record dimensions, features and specs.
We stay on top of new products and technologies to help people make informed choices.
Overview: The Rockford Fosgate Power T500X1br is an ultra-compact
mono-block amplifier. Even though the amplifier is only 8-5/8" x 4-1/4", it
puts out a full 175 watts x 1 at 4 ohms, 300 x 1 at 2 ohms, or 500 x 1 at 1 ohm.
Class BR: The amplifier features Rockford Fosgate's proprietary Class
BR technology, which stores energy until it's needed, then delivers extended
bursts of power. The patented Boosted Rail technology provides increased
efficiency and lower distortion.
Constant Power: Rockford Fosgate uses a patented circuit design to
gain up to 25% more output power. Constant Power actively increases the voltage
and current in direct relationship to the rise and fall of music signals to
provide additional power.
Fan Cooled: The T500X1br features dual fans to keep the amp running
cool. Dual Fan Forced Induction pulls in fresh air, which pulls heat off of the MOSFETs, and directs airflow into the exhaust channel and out of the amplifier.
Since the top and bottom heat sinks are decoupled, the top remains cool to the
touch. When installing, you should leave at least 2-3" of clearance around the
ends of the amplifier to optimize air flow to the fan intake and exhaust vents.
C.L.E.A.N. Technology: Using Rockford's C.L.E.A.N. (Calibrated Level
Eliminates Audible Noise) technology, you can easily and precisely set up the
amplifier levels to eliminate distortion from damaging your speakers. Simple LED
indicators are used, instead of test equipment, to identify signal clipping at
both the input and output, and to match the audio source to the amplifier.
Top Mounted Controls: The T500X1br features easy-to-reach controls on
the top panel of the amplifier. The controls include:
- Input Level: This rotary control lets you match the output of the
audio source to the amplifier. A small screwdriver (not included) is
required to set the levels.
- Input Level Switch: You can select the type of input
you're connecting to the amp. When set to LOW, the input sensitivity is
150mV to 5V from the line level outputs of the source unit. When you switch
to HIGH, the input sensitivity is 300mV to 12V from the speaker level
outputs of the source unit.
- Punch EQ: The Gyrator-based Punch EQ eliminates frequency shift
with boost. It functions as a 0 to +18dB variable Bass Boost at 45Hz. A small screwdriver (not included) is required to set the
amount of boost desired.
- Frequency: The Butterworth crossover is internally set
to Low Pass, and the cutoff frequency is constantly variable between
50Hz and 250Hz with a slope of 12dB/octave. A small screwdriver (not included) is required to set the
LED Indicators: The amplifier has three LED indicators on its top
- Input Clip Indicator: The input clip indicator works in
conjunction with the audio source's volume knob. It will illuminate red when
the audio source reaches its clipping point.
- Output Clip Indicator: The output clip indicator works in
conjunction with the amplifier's input level knob. It will illuminate red
when the output level has reached the clipping point. When setting the level
using test tones, you should adjust the output level until the LED glows
blue. If setting the output level using music, the LED should glow blue with
only an occasional red indication.
- Power/Protect: The Power LED illuminates blue when the unit is
turned on. If the LED turns yellow, a short circuit or too low of an
impedance has been detected at the speaker connections. If the LED turns
red, the amp has overheated and has shut down.
Left Side of Amplifier:
- Remote Punch Level Control: This RJ45 jack lets you plug in the
PLC2 Punch Remote Level Control. The control needs to be switched to the
ON position in order to use the remote level control.
- Inputs: The 4-pin Molex connector works with the supplied RCA
Input Harness. The amp will accept signals from either high-level (speaker)
or low-level (RCA) sources. If connected to a high-level input signal, the
amp's auto turn-on feature is active.
Note: For high-level input, you can either splice RCA plugs onto the
source unit's speaker wires, or cut the RCAs off of the supplied input harness and
splice on speaker wires from the source unit using the standard wire color
code (left=white, right=gray).
Right Side of Amplifier:
- Power/Remote Terminals: The amplifier's Power, Ground, and Remote
terminals are located in a separate plug-in quick connector. The connector
has compression terminals that will accept up to 8-gauge wire. When
utilizing high-level signals for the auto turn-on feature is active, and the
Remote terminal can be used as an output to turn on/off up to two additional
amplifiers or other accessories. A small
screwdriver (not included) is required to tighten/loosen the compression
terminals. Once the wires are installed in the quick connector, the
connector can be plugged into the amplifier.
- Speakers: The speaker output has removable compression
terminals that will accept up to 10-gauge wire. A small screwdriver (not
included) is required to tighten/loosen the compression terminals.
Warranty Terms: Rockford Fosgate Power-series amplifiers
carry a two year warranty, when purchased from an Authorized Rockford Fosgate
Extended Warranty Offer: Rockford Fosgate offers a one-year
extended warranty (for a total of 3 years) when the amplifier is installed using
a matching Rockford Fosgate installation kit, such as the
