Stereo speaker placement idea you might like, 6 speakers, sounds great even with no roof on! Options

I have two speakers on each side in front, one in the original footwell location and one in the door, wired together in series as one channel. Each pair make up the front left channel on one side and the front right channel on the other side. Then I have two speakers in the center of the backrest. One is the left rear channel and one is the right rear channel. When I balance the music out from front to back, it's really easy to hear the sound because it's coming from very close to your ears in the backrest. The front two speakers on each side compensate for their inferior position by being paired for each front channel. Don't need an amplifier. Works better than I could have hoped! (Might also notice the velcro strap around the fuse cover to keep it from being bumped off accidently)

There is that much difference in sound using the doors. Do a little research on enclosures and air movement in speakers and the question will answer itself. Besides, How many modern cars do not use the doors?

I won't cut my door cards but know if I did the music quality would improve dramatically. Just trying to preserve what little originality I have left.
