Which of these plots would give me the best overall bass with kick drums?

Up the Vb a bit, and you'll get a more pleasing response curve, and thus a better response.

And where the hell can you buy a mono a/b car audio amp?

Hifonics BXi606

PG Ti 1200.1 and 800.1

No amplifier types are inherently bad, they just have different advantages and disadvantages. Chances are good that with subbass, you probably (don't hold me to this) won't even notice the difference in the first place.

Class C's pretty **** bad, even for subbass //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

A big suckout in the 40-100 hz region with a peak at tuning is pleasing? The bigger the box with that tuning the more pronounced the peak gets. Interesting...

Considering that they are non linear...yeah, pretty **** bad covers it.

I said to raise the volume, not keep the tuning the same. The Fb will drop then, which SHOULD remove that beautiful node there.

Hmm, never heard a class c. Only A, A/B, D, and G.

really? what the hell is class T? does it **** and is better than D but worse than a/b?

What would you suggest he do to the tuning? Are you saying keep the port length the same and increase the box volume, thus lowering the tuning? If so, that's what all the other plots there are. They create a nice shelf where the entire sub-bass region is 1-2dB down. Again not exactly optimal.

None of them are optimal, but I made a box for two rlps and 3 cubes net for both came out to be far too small for them. I remade it at 4 cubes at 30hz, and it was simply amazing.

I would think a good 3 way component set or really nice 2 way would work better than subs.
