Yes, it is for the Miata.

Zero room under the seats, I had to remove them to put on seat covers.

I sealed the doors and speakers with duct tape (not the cheap kind you get at Home Depot, the heavy duty industrial type).

I did install the cup/baffle things behind the speakers.

Good to hear I don't need to reopen the door panels, they are not much fun to remove.

The Quart speakers get good reviews so I don't think they are the problem (however they are rated at 100-200 watts so I am guessing not very efficient).

Thanks for the validation, I will go forward with the amp install project and see how that sounds. Pretty sure I can install that in a day with just pulling out some carpet and running a bunch of wires.
