I recently purchased this product and replaced two other amplifiers that I had (PowerBox 60.4 V7 4 Ch. A/B) for vocals and (Hertz HCP 1D) for a 12" sub. I set it to the max RMS watts of the speakers (80W and 250W for the sub) using a multimeter and the sound is very good. (The only thing I had to change afterwards, which I hadn't calculated, were the speaker cables because the old ones were thinner and caused distortion at the terminals.)

The sound is very clear (if properly adjusted) and compared to economical A/B amplifiers (like the vibe I had), the sound is cleaner and more intense, especially in the high frequencies (although less "sweet" since it is class D).

I highly recommend it to anyone who doesn't have space in their vehicle because it can easily be placed under a seat or in any other spot since it takes up very little space. It is also easy to remove if needed, as everything is connected with plugs, and someone can safely disconnect the cables and remove it (perhaps for cleaning purposes in the car, for example).

Postscript:

The vehicle I use does not have air conditioning, and during the heat of the summer days, it managed the temperature very well. It would decrease in intensity to cool down on its own, and I could tell, but it never stopped functioning due to thermal protection.
