Low Noise Preamplifier Circuit - Maximum low voltage signal from the source unit comes into the amplifier through a low voltage circuit which delivers minimal distortion through the amplification process.
RCA Inputs - Nickel-Plated RCA jacks that create the best connection to prevent interference and minimize distortion in the signal path..
Hi Level Inputs - Easily tie into OEM audio systems that do not offer RCA outputs.
Crossover Type - Variable Electronic Crossover - 12dB Per Octave
Output Device Technology - Exclusive Crunch SPEED-FET MOSFET components maximize power efficiency while improving sound quality and minimizing distortion.
Heat Sink - QTD Technology Aluminum: Quick Thermal Dispersion Technology assures additional mass in the aluminum heat sink keeps the amplifier running cool with nearly undetectable distortions during normal music listening.
Power Supply - High energy Pulse Width Modulated Power Supply delivers power with minimal impact on the electrical system.
Electronic Equalizer - Control of amplifier output with on board electronic crossover to tailor specific frequencies to speakers and subwoofers.
Output Connections - Nickel Plated Brass Connection with terminals allow for secure connection while resisting corrosion.
Connection Type - Screw Down Connectors: Easy access for hand tool allowing a quick and secure connection.
LED System Protection Circuitry Diagnostics - Monitor overload and speaker short protection with illuminated indicators on the amplifier end panel.

I bought a 3500 watt class d one channel crunch amplifier and it was supposed to be one of the best they have. I know RMS watch drop down to around 800 on an amp that big maybe even 600 that's fine. I am so upset with this amplifier... I took it to a audio shop and had the pequots and the RMS Watts tested and the peak was only ran to $642 Watts. And RMS didn't reach over 250.. It's supposed to be $3,500 w class d. With a full bridge I should be getting the whole 3,500 to one speaker. Will it hooked at one channel I should be getting 1750 Watts. I don't understand I did not get 115th of what I paid for. I don't care if the damn thing lights up I'm not looking at it when I'm driving anyway it's in the trunk. I guess it's in the trunk cuz it's jump. If I get a new one it's standing inside the car. It will not be crunch either. I did some investigation on some other peak power and RMS pools on amplifiers and stinger is killing it. Why don't you follow a little of their diagram and you might get somewhere.. by the way I did own both of the amps. I got rid of the 2000 watt class d because I wanted a bigger one and I really think the 2000 watt harder than the 3500. It is kind of crazy I wish I would have did a test on the 2000 w before I sold it. I will never buy this brand again.And I encourage anyone else not to buy from crunch.

I installed the amplifier, and I am blown away by its performance! With 1500 watts of power, it delivers crystal-clear sound and deep bass that truly enhances my audio experience.The installation was straightforward, and the build quality feels solid and reliable. I appreciate the versatility of this 4-channel amp, allowing me to power multiple speakers with ease. The sound quality is impressive—everything from highs to lows is well-balanced and rich.If you’re looking for an amplifier that combines power, clarity, and affordability, the GP-2000.4 is an excellent choice. Highly recommended for anyone wanting to elevate their car audio setup!
