AMP MASS FR52
The AMP MASS FR series was designed specifically for those people who are looking for loud sound in their car, but are not yet ready for serious modifications to their car.

The FR model range includes almost all sizes of acoustics used in cars, from 10 cm to ovals 23x15 cm.
This AMP FR52 model, measuring 13 cm, is installed in a regular place in the kick panel or door, is not very demanding on volume, and is capable of reproducing sound at a decent volume already from 120 Hz, in order to achieve maximum output of this speaker, we recommend a cutoff of 150 Hz in the 2nd order. The sensitivity and nominal power of the speaker allows you to add it even from the HU.

And the upper limit of the frequency range of 15 kHz allows in some cases not even to use tweeters.
