6 ohm speakers with 8 ohm system???
What would happen if I used 6 ohm speakers with 8 ohm system?
I just bought a JVC surround sound system to replace my Panasonic. But, the Panasonic has 6 ohm speakers and my JVC say it need 8-16 ohm speakers.
Would it blow my speakers or the JVC system (or both)?

It could harm your receiver depending on the volume you are trying to produce.
Does the receiver have an ohm switch? If not, I would watch the volume and the temperature of your receiver carefully.

The impedance of speakers varies widely as a function of frequency. The impedance rating (and the frequency at which it is rated) are little more than a general guide. The impedance is generally higher at frequencies other than the rating frequency.
At or near the power rating, you are a little more likely to get distortion and overheating. If you have plenty of reserve power, I wouldn't worry about it. (you probably do unless you like real loud.
Six ohms is an unusual impedance. If you do buy a new receiver, look for one that can drive 4 ohms well.
In the meantime, the only controllable variable is the speaker wire you interconnect with. Speaker impedance can affect damping ratio, and I would recommend about two wire guages larger (lower number numerically) than would otherwise be recommended. For example, if length would normally dictate 16 AWG, use 14 AWG. Absolutely, do not connect 2 ohms in series to get to 8 ohms; that will really scrw up damping ratio.
