I’m no expert but if you soundproof the boot. Don’t you need to be IN the boot then to hear your subwoofer?
Good point. What I mean to say is that I don't like the bass to be heard outside
the car via the boot lid, which is very thin. I also don't like vibrations in
the car via the plastic boot / roof / side panels which tends to dissipate the 'punch' of the bass and makes it muddy and boomy.
This can make the bass reverberate far too long instead of a short punch - depending on where your frequency, phase and cut-off are set..etc…. Of course I want to hear it in the cabin
, and as it's such a small car, even my small sub-woofer can be heard very, very easily,
but I like it to be controlled, punchy, not boomy
and kept as much as possible within the car as a whole. I don't want the general public listening to my Steely Dan, TOTO and deadmou5!
I'm no expert either, quite the opposite, but I used to drive a van around London in the late '80s and had a sub in the back that was fun but boomy! My friends taught me about sound deadening the van and sound proofing the panels to tighten up the bass and it sounded much better. Plus it stopped me sounding like an idiot when I drove around sounding like a sonic boom. So I'm going to 'apply' the same principles on my car and see if it helps tidy up the bass, internally and externally. I'm open to any advice on this subject so if you have any experience then please share.
