I have bought this particular item twice. The best you can get for its price. Both times I bought it for 140 euros from a well-known chain.

The whole car shakes, I didn't expect it, it's the best for its money, buy it with your eyes closed. I have it on one channel + and on another channel - so it plays even louder. You can hear it both outside and inside, it's crazy bass for its price

I bought one along with an amplifier and we have shaken the whole place and I am getting ready to install a second one with an extra amplifier and capacitor! Of course, after that, I won't have any free trunk space, but it's worth it!! I have gone through speakers and speakers due to work and I have spent thousands of euros, but this Alpine for this money delivers pain! Value for money, therefore, and the whole car shakes! Choose it without hesitation!

value for money! very strong

It was installed on an A4 B5, very powerful, everything creaks for the 175W it takes, it gives a lot of pain. It was connected on top of a Sony 4-channel

Very good and powerful, I use it at low volume and it plays very nicely and sweetly as the build quality is evident. It takes up a lot of space in the VAG group small car trunk, definitely losing 2/5 of the trunk space. Whoever wants something very powerful and of quality, this is it. Whoever wants to hear just bass should go for the 8-inch Alpine, which has a similar setup.

The best value for money, very high-quality sound, I've been using it for 3 years and it still plays like new

I had heard it in a friend's car and I was very satisfied. I also installed it in my own car, driven by a 130w amplifier, and it plays very loud and clear.
One of its major advantages is the fact that it can be used both as a bass reflex and as a sealed box with a removable lid in the bottom slot. Personally, I use it sealed for more control in all genres of music, but if you want to give kicks to the rear passengers, you can work it as a bass reflex.
