Does that sub get very hot sandwiched in that slot?

So I gave the 10" Kicker a try yesterday to see if it had any better low end response than the 8" version and was rather surprised when it performed... worse? I only had it for a few minutes as I tried the demo model at CarToys but doing an A/B comparison the 8" sounded better in all aspects. The 8" also fits between the false floor better, so I'm going to stick with it.

Unfortunately iPhone doesn't allow a global EQ setting and the only app I use that allows for 32hz EQing is Plexamp but I put a +6 boost on 32hz but a -2 reduction on 64hz to have a sharper roll-off. This seems to fill a little more of that very low response gap.

I think unless I go with a custom install there's not much more I can do to improve it. Will I do that in the future? Very unlikely, as this now covers the majority of the content I listen to. I don't listen to songs with prominent ≤ 35hz bass often... I've probably listened to more of it in the last week for testing than I have in the last 4 years.

It may be that 8" is all the improvement you can get. Bass needs room/space to resonate correctly.

Here's an interesting implementation.
