GM-DX874 4-Channel Bridgeable Amplifier with Bass Boost Remote

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.

Added to a 2022 Mustang to power a 10" subwoofer, and 2 two-ways in the rear deck, to upgrade the existing "Bang and Olufson" stereo. Generally good results, after using a pre-amp DSP (AudioControl LC2i) to sort out the signal from the stock head unit. Has plenty of power, setting the gain about 40% level. The low pass and high pass filters work well, and I was able to custom tune to my ears. This is not a high end Amplifier, and you can find others that will cost you double or triple. For my needs it was perfect when you need just better and cleaner sound.

Das Gerät gibt alles was geht ist geil

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.

Awesome amplifier! Pioneer is the factory, amplified sound system in my car. I replaced all speakers and amplifier with updated Pioneer units. This amp for great in the factory location even though it's slightly bigger, but not too big that it wouldn't fit on the factory amp bracket. I recommend.
