Best components/midbasses for system with no sub?

[sportyaccordy 10+ year member]

I have an 09 Civic sedan without the rear deck sub. I want to upgrade the stereo, but I don't want to do a sub. I need my trunk and to do it how I want (single 10-12" tuned to 30Hz) will take up too much space and add too much weight.

What component systems will net me the most bass? I will definitely dead and seal my doors. I am seriously considering getting the rear tray out of an Si to get the 8" factory sub mounting location as well. I have heard good things about CDTs, but looking at the specs the FS & frequency ranges seem high. I know this is probably impossible but I would like 6.5s that could reach down to 30Hz or maybe even a little below.

This is not realistic without building an enclosure into the door. We play subwoofers below Fs out of necessity, but even a 6.5" subwoofer is going to have a problem of playing loudly and playing deep bass when installed into a door. I can say this from experience, as I installed CDT HD-6MDVC 6.7" subwoofers into my own car and it just did not work out well.

There are small loaded subwoofer enclosures from many reputable manufacturers, and I recommend you take that into consideration. The JL CP108LG-W3v3 8" ported sub we have is a great example.

He's right. It just won't happen. DD has a monster 6.5 sub that you can put in the trunk. It won't take much space and give you 30hz playback.

There is an MTX Thunderform enclosure for my car, but naturally it's sealed and only has 1.3 CF of volume. F3 will be high AF. Again I know it's a tall ask but if I went with a loaded enclosure I would want something small with low extension good for 300-400W RMS. Again, a tall ask. Any other recommendations?

I have heard half decent OEM systems... my wife's Rabbit for example seems like it could be satisfactory with no sub and just higher quality speakers with a separate amp. So I might be overstating my requirements.
