If you do not have the knowledge to install a traditional amplifier, this one is way easier !!!
Simply a plug and play installation and that’s it.
No need to wire it directly to the battery, it will get the needed power from the ISO connector of your headunit.
Used for 2 Hertz 6.5 55rms and 2 JBL 4.0 70rms
Works like a charm, definetly recommande it !

After a lot of thought, I bought it. I have to say that it produces a lot of intensity to the point where I can't turn it up all the way because it seems too loud. The sound is very clear and nice, the mids and highs showed quite well as before they were a bit lost in the bass. The bass is also quite good for a car without a subwoofer. When I turn it up all the way, it's like getting kicked in the chair. Overall, I had some doubts but I think it's the best purchase one can make for this money. I have a 2013 polo, and I have installed pioneer ts-a1600c (80rms) in the front and ts-a1670f (70rms) in the back, an eonon screen, and the amplifier.

Unfortunately, in the Grande Punto with Blue&Me, it is not "Plug & Play". Firstly, there is a difference in the cables as you can see in the photo. When the source is connected, it shows "CANCHECK" and you can't do anything.
Presumably, the two cables need to be changed as you can see in the pictures with the red circles. The source has them on the left while the amplifier has them on the right. I didn't want to try it because I would probably lose the warranty.
Unfortunately, I returned it.

In a source from 2010, it was first tested (photo), and then regularly, so simple, so easy.. It was chosen due to the narrow space in a two-seater.. All these compact theoretically are for boats.. Get it, you won't regret it... Purchased for 130€ a month ago.. May '23

For the size, it is very good! I didn't expect such powerful and clear sound, I have the gain almost in the middle and they play amazingly! It even enhances the factory speakers. And the great positive.. It fits everywhere in the dashboard and doesn't require extra wiring.

I was expecting a slightly better bass, to tell the truth, while my speakers are good (JBL) and quite high-quality. However, it is very small in size and definitely the fact that you don't need a battery line is very useful.

Update: If you use RCA inputs for sound instead of the ISO plug, the bass is significantly better and fuller.

Very good and in intensity but also in quality!
A very good solution if you don't want to pull cables from the battery to the back of the RCA, etc... It plugs into the ISO fuse and you're ready to go

Initially, it is a very good solution for someone who does not want to deal with connectivity, it is simple (it connects directly to the car's cables) and it is awesome! I was in a difficult position and after searching a lot, I hadn't found an objective evaluation anywhere, nevertheless, I was amazed by the final result. (I have a Chinese Android source combined with high-quality aftermarket speakers in the medium range market)

Positives:
1) It produces tremendous sound quality (in combination with good aftermarket speakers)
2) It produces tremendous volume and clarity
3) It is qualitatively sturdy and beautiful, you can fit it almost anywhere and it gives you gain options for the channels so that you can adjust it where it should be!

Negatives: It simply doesn't have any!
