Our take on the Pioneer GM-5500T by Crutchfield's Ken Nail
Looking to upgrade your system's sound? Whether you're ramping up your aftermarket receiver or adding much-needed power to a factory radio, you can count on Pioneer's GM Series amps to deliver what you're looking for — clean power. Power that'll bump up the bass, sharpen the highs, and make your listening experience something you'll look forward to every time you turn the key.
The GM-5500T 2-channel amplifier is well-suited to drive a pair of high-performance coaxial or component speakers, with 125 watts RMS per channel. You can also bridge the output of this versatile amp to punch out 400 watts at 4 ohms, and you'll find a low-pass filter that adapts the amp to driving a subwoofer. Speaker-level inputs allow you to add the GM-5500T to a factory stereo.
First of all if this amp isnt pushing a 10 then I'm sure you have something wrong cause I have 2 of these and they pound hard but yes they do get hot but believe me they do there power rating if not more...great amp for the buck
old school 68, tulsa,ok

CEA-2006 Compliant: CEA-2006 is a system of testing and measurement methods for mobile audio amplifiers, this voluntary standard advocates a uniform method for determining an amplifier's RMS power output and signal-to-noise ratio. The criteria for measuring power uses a 14.4 volt DC power supply and the RMS power output is measured with 1% or less Total Harmonic Distortion plus noise (THD+N) over a frequency range of 20 Hz to 20,000 Hz (for full range amplifiers). Signal-to-Noise ratio is measured in weighted absolute decibels (dBA) at a reference of 1 watt into 4-ohms. The CEA-2006 criteria allow consumers to make an apples-to-apples comparison of car amplifiers and receivers, even from different brands. Manufacturers who adhere to the standards can display the CEA 2006 logo on their products and packaging. CEA2006 Specifications:
- Power: 125 watts x 2 into 4-ohms
- S/N: 78 dBA (@ 1 watt into 4-ohms)
Gain Control: To accommodate the varying range of signal levels coming from today's factory and aftermarket radios, the input gain is adjustable (200mV-6.5V line level, 800mV-26V speaker level).
Gain Control Caution: If the gain control level is set too high, Pioneer's Gain Control Caution feature will automatically reduce the amplifier's output until the headunit volume is decreased to acceptable levels. This added layer of protection helps prevent damage to the amplifier and the connected speakers due to improper gain control adjustments.
LPF: A two position switch turns the low pass filter (LPF) on/off.
Frequency: The low pass crossover point is continuously variable from 40 Hz to 500 Hz. The crossover slope is 12dB/octave.
Bass Boost: The Bass Boost circuit is centered at 50Hz and can be set to 0dB (off), +6dB, or +12dB.
Power Connections: The power and ground connections are 0.545" wide screw terminals, the remote turn-on screw terminal is 0.325" wide. A Phillips-head or flat blade screw driver (not included) is required to tighten/loosen the terminals. Spade connectors are recommended for the power, ground, and remote wires.
Speaker Connections: The speaker screw terminals are 0.325" wide. A Phillips-head or flat blade screw driver (not included) is required to tighten/loosen the terminals. Spade connectors are recommended for the speaker wires.
RCA Input: The amplifier features a pair of stereo RCA line level inputs (left/right).
Speaker Input: The GM-5500T's speaker level input and harness allow you to connect your OEM radio (or aftermarket radio that does not have the typical RCA-type outputs) without having to buy an adapter.
Fuses: The amp is protected by two 25-amp ATO blade fuses.
