I have done a full all out separation from the coil.... The rest was
intact, the coil was toasted bad. Yeah, there ya go. that is what I
was reaching for.... Yes, I always check my THD ratings.... I never
knew the full name, but I knew it was a percentage of distortion at a
certain output power. Yeah, the more you twist that gain on the amp
(amp, radio, any outputting unit in the circuit) the closer you are
getting to a dirty signal (distorting it...). I suppose as long as you
control your gains and stay away from the distortion at the top of the
gain.... You won't have problems with your speakers..... In the Ram
the speakers were always over qualified for the stock radio, just in
case....

>> I always shop knowing my RMS and MAX values. The
first thing I do is make sure my total peak/max power driven to
my
speakers is less than the RMS of the speaker itself. I have
blown
several speakers (MTX was the first set, hahahahaha) not paying
attention to that amp.
While it is possible to blow speakers from too much power
(actually
tearing the cone from the spider), it's extremely difficult.
However,
it's way too easy to blow speakers from too much distortion.
Distortion
is measured in % of THD (Total Harmonic Distortion) at a
particular
wattage output. Lower is better, preferably .1% or lower. When
shopping,
I TRY (but don't always succeed) to get an amplifier that equals
or
slightly exceeds the power rating of my speakers (both in RMS,
of course),
with very low distortion. If you go lower than the rated output
of your
speakers (assuming a quality amp), just make sure you don't have
to turn
up the amp too far. If gain must be set above about 5/8 or 3/4
to get
sufficient output, you have an underpowered amp. The closer you
get to
the top of the gain knob, the more distortion. The very best
systems run
with the gain at the lowest setting (turned counter-clockwise
all the
way). Mine doesn't, because I'm cheap (it's around 1/2 of
maximum). My
