American Stereo Integrity BM IV subwoofer 12" paid 500 euros, exceptional performance, especially in low-volume speakers.
Fiberglass Sub Case, adapted for Nissan Qashqai left trunk side from 2014 to today, paid over 350 euros
The case does not take up space in the trunk, thanks to the fact that it is mounted on the wheel arch.
850 Euro total value
I will sell for 350 euro + 40 euro shipping cost to UK.
Technical specifications of the subwoofer:

Product Description
We pulled out all the stops and have designed, and tooled, all critical components from the ground up. The BM mkIV has 14mm of one-way linear travel, a massive 10” diameter spider, 8 layer copper voice coil, proprietary two piece flat diaphragm, a shorting ring, and a 10 ring neodymium cluster magnet structure. We have shoved all of that technology into an incredibly compact package of only 3.2” deep. It also requires only 0.5 cubic feet of sealed enclosure space to achieve optimum performance.
The BM mkIV is setting a new standard for sound quality subwoofers, both for shallow and regular depth. The BM mkIV has the ability to reproduce deep, articulate bass while at the same time totally disappear giving you the impression that your front speakers possess massive amounts of low-end response. Not being able to pin-point where the subwoofer is located at is exactly what a top notch sound quality subwoofer should do – and that’s exactly what the BM mkIV does.
If you are after the pinnacle of SQ with good output, this is it.
