It's been a while since I've pulled one of those, but isn't it removed
by poping the screen off the top then removing the 4 8mm head nuts?
Speakers are easily tested with a 9v battery. Attach two wires to the
speaker then touch them to the terminals on the battery very very
breifly. The speaker will emit a poping sound as you touch and as you
remove the wires. This trick is also great when installing a new radio
to identify which wires in the car lead to which speaker(s). You can
also test the speaker with a multimeter set to measure resistance
(ohms) or continuity. Open circuit means a bad coil, 2 or 4ohms
(depending on the type of speaker) represents a good coil (though
there could be other issues such as a detacted cone).
Hey Huw if you are reading, just for referance, household speakers are
generally 8ohm aren't they? <insert plug for Human Speakers>
