Afternoon all, Looking for a little bit of advice. I had an LG surround system, 5.1 system, non-powered woofer, with a built i dvd player. The amp itself is fooked, so i've acquired a Pioneer VSX421: Pioneer VSX-421 The rated impedance at output level is rated at 6 Ohms. The speakers i'm using, from my LG setup are quoted as being 4 Ohms. Is this likely to cause me any issues? Am i likely to cook my amp? Apologies for what is probably a simple/stupid question, this is not really my "thing" And thanks for any replies Doug.
