Pioneer GM-DX874 1200W Max 4-Channel Class-D Stereo Car Audio Amplifier

Great customer service by 1156425 Ontario Inc who took back this amplifier, thank you very much for that. The amplifier itself, if you like to listen to music is a very poor amplifier. The signal to noise ratio is absolutely terrible, which means that listening to jazz at low volume, you hear a lot of pink noise in your speakers. BUT it's capable of driving speakers to make a lot of noise for a low price. If you want high volume and to impress people, yes, if you are a fine listener, no.

Das Gerät gibt alles was geht ist geil

Over all gud amp

This amplifier is the best I’ve ever had, and I’ve had a few, it doesn’t go into heat protection mode after 2 minutes, like class a/b amplifiers. It makes the seats shake when turned a bit higher and I haven’t noticed any distortion. I thought I heard a rattle, but it was the interior light lol! This amplifier can power big speakers(150 watts rms) my previous Sony amp could not keep the power up more than 5 minutes, and there was hardly any midrange frequencies. Honestly I can’t turn it up to full volume because it’s too loud.

Hi! Last Friday (sept 19), I attempted to get the amp professionally installed to upgrade my existing fully functional/operating truck stereo (4 speakers and 2 subwoofers). Unfortunately, when the installer turned on this amp, there was a popping sound/clicking sounds and then a high pitched whine.......there is now a blue flashing light? The installer immediately turned it off and said he has only had that happen once before in his over 20 years of car stereo installation.....installer checked all wiring and had no issues! I am working with seller (GTA Electronics) for free replacement.....will update this review afterwards!
