The previous owner of my Miata installed a monsterous stereo system
consisting of mis-matched components, DVD player so he could watch
"Deep Throat" on the screen while driving and a many billion watt amp
in the trunk, all installed by a drop out from plumbing school who had
absolutely no clue as to what he was about.

As I mentioned some weeks back, the DVD crap is gone, the amp is gone
and the current install is a stock 1992 Miata radio/tape player.  The
headrest speakers are now working perfectly (apprentice plumber didn't
know what the wires were for so he just cut them....) but the door
speakers have the cones ripped to shreds by the amp or maybe by
vibration?  Plumbing school dropout figured he didn't need all those
screws to hold the speakers, maybe one or two would be enough(!)

I need new door speakers but my budget is now shot.  I understand these
are 6 1/2" speakers with 3 mounting holes and Mazda wrongly believes
they are worth wau more than speakers of that quality should cost so...

What's a good replacement speaker?  Let's be a little reasonable here,
it's a convertible that almost always has the top down, it has no sound
proofing, it is capable of creating it's own racket with exhaust, some
rattles, etc.  Fidelity is further compromised by cars with loud
exhaust, low riders with rap "music" cranked up, sirens, horns, etc.  I
don't need or want a $5,000 sound system, I just want two good,
inexpensive 6.5" speakers that will allow me to listen to a ball game
with out the buzz I get from the torn cones.

I'd really appreciate suggestions for speakers that will bolt right in
w/o modification and won't cost too much along with information on
where I can buy such.

TIA!
