question on ohms

[Doc Voodoo]

What would a it take to run a subwoofer that is 6 ohms . All the amps that I look at are for 2 -4 ohms. These are MB quarts and they top out at 175 watts. But there cheap so I was wondering.

easy...

Buy 2 of 'em and run 'em in parallel for a net 3-ohm load.

Or...

Just buy one of 'em and run it like it is at 6 ohms. It just won't get as loud - you'll get less wattage out of your amp.

run two, otherwise the amp will just put out less power at 6ohm than at 4ohm, wont affect sound quality though.

yep

It just won't be quite as loud (possibly a 1-3 dB difference).

You could run two speakers in parallel/channel on a 2 ohm stereo stable amp (if you have 4 subs). Each channel would see 3 Ohms. With both channels that would yield 4 speakers (2/channel). You will lose ~1-2 db because of the increased resistance (and therefor decreased power). Probably not noticeable if the amp is powerful enough.

175 Max power is not a lot. What is the RMS on those? about 100 watts?
