[Shotimes] Another blasted stereo question

[Bill Murray]

You are corrent that an amp will not "put out" a 4 ohm load.  But it is
rated at a certain amount of watts at a certain ohm.  Most car amps are
most stable with a 4 ohm load, and the RMS power rating that
manufacturer gives, is with a 4 ohm load.  The lesser the amount of
ohms, the more watts the amp will put out, but the harder it will work
to do that.  This results in more heat from the amp and more distortion.
Some older car audio amps, Orion HCCA 225, were stable down to .25 ohms,
but they could get so hot that the internal solder joints would actually
melt.  You should match up your speakers to an amp that can handle the
load that the speakers present.  That is why I recommend replacing the
JBL speakers and amps at the same time, since the JBL speakers are 6
ohm, but a 4-channel, Sony amp for instance, will be 4 ohm rated.

What does it mean to say that an amplifier is "putting out" 4 ohms?  How
does an amp "put out" resistence?

Yes, if you have the JBL system, I'm pretty sure the speakers are 6 ohm
and
the Rockford is putting out 4 ohm...
