As we all know, OEM Bose systems have speakers that are very low
impedence...1/2 ohm, or 1 ohm, or something like that.

Is there any way, in terms of adding resisters and the like, to lower the
impedence of regular speakers from 4 ohm down to 1/2 or 1 ohm? Something
that I can do myself and be able to replace the Bose speakers with my own?

Or, if this isn't possible, are there any manufacturers out there that make
very low impedence speakers?

Excuse my ignorance. I've always been ohm-challenged.

puttin resistors in-line does very little, becuase while it drops the
impedence, half the power just gets wasted through heat through the
resistor anyways, so there is really no extra power going to the
speaker.

all you can do is replace the speakers and take the power hit, or else
replace the head unit and/or get an external amp to power the new
speakers.

lowest speaker impedences I've seen are 2 ohm, by infinity kappas,
orion HCCA's, and I think image dynamics made some. but buying for
impedence only is sort of the worst way to buy because it has no affect
on sound (given the same power).

Thanks for your response. I understood everything you said except for this
last sentence (see above).

As long as your amplifier doesn't overcurrent, there's no reason it
can't run a 1 or 0.5ohm load. Try it out. That is pretty darn low, but
keep the gain low and give it a shot. You might be fine. If the amp
cuts out or goes into protect at high volumes, then it's pretty clear
it can't support that load.

Of course, this only works if the amp has good overcurrent protection.
Every amp should have, but it's possible some amps can't fully protect
themselves. Try it at your own risk.

Eezip,

This has nothing to do with trying to run any amps at low impedance loads.
I'm trying to find speakers to replace the Bose speakers, which are 1 or 2
ohms, or something like that.

Not good advice, I'm afraid Tony. I know EEZIP means well but I blew an amp
once (a Rockford Fosgate Punch 75, an amp KNOWN for it's reliability) doing
EXACTLY what he is recommending. But then again, I have seen others who
have done this with amps not rated for those impedences with no problems.
Of course, it all depends on the amp, but THERE ARE DANGERS. Frankly, if
you value the amp, I wouldn't do it.

Oh, sorry Tony. I didn't read this message before I posted the other. Oh
well, what I said still stands of course.

See ya,
