This is a review only to the product and not to the seller because I bought the subwoofer at the Essen Motor Show. The product is, as usual of Hifonics, very well made and very solid. The size is for placement under the seats really suitable if you still want to treat yourself to something footwell rear passengers. I got it in my built in the trunk (see photo set). I drive an Opel Vectra GTS C and there is in the side trim of Kofferaums a trough into which the subwoofer ideal reinpasst. The bass, the device provides, is sufficient for my purposes from perfect, it is not so much the same throughout the car rattles but the overall sound is much fuller. I had only remember because my car and the trunk are quite large but as I said, it is quite enough. The attachment was in my case, but rather mühseelig since I mounted it on an uneven surface, though I had the small metal plates that are actually bolted to the sub, not used and had the screws from the rear through the side panel of Kofferaums directly in the housing of the subwoofer Screws, making a disassembly very problematic, since I only have to disassemble everything again: - / However, this should be on a flat surface theoretically no problem.
