Awesome sub, it's worth it and more
I haven't even adjusted it halfway
And the car rattles all the time
It fills the car space very nicely
Small and very powerful
And it has been installed in the factory source without changing anything
Easy installation (I installed it myself)
Just need to have handy tools
Installed in Opel Astra OPC

I was looking for a subwoofer with quality being the first priority and not quantity.
Just before, I had installed four Hertz subs, so I decided to go with the company's sub.
The result is AMAZING.
I was afraid that the eight-inch woofer might not be enough for an SUV (Terios).
But it seems capable of filling two more cars!
Powerful and high-quality.
During installation, they set the Gain at 60% and it blew my mind.
Eventually, I lowered it to 35% and I have also cut the bass from the EQ!
And all this despite not being connected to the sub output due to a source problem.
A small sub with a big sound.
EXCITED.

Amazing subwoofer! Very satisfied, I have installed it in my Nissan Xtrail T32 and it has a very good sound!!

Together with me and anyone else who heard it (everyone has sound in the car), only positive comments were made, they were impressed.
