Yes there are also good underseat-subwoofers, that's right.I was preparing to make a gag about not being able to tell the difference on my tiny desktop speakers, but hats off to you - it genuinely does sound better even through a youtube video played through tiny desktop speakers. I'm becoming increasingly convinced of the benefits, although I think i'd probably want something to go under the passenger seat. Boot space is at a premium for me. Great job though, looks super clean with that false floor.
I still have same space as before [except the bag], and even the bag could be "down" next to the subwoofer if I need some more. In the video, the sound sounds a bit distorted and strange, but that's not the case in real.
