Hi.....quick question for people cleverer than me...(of which there are many). I have recently acquired a TEAC Cd/receiver CR-H230 which drives two 8 ohm mission speakers and a PIONEER S-W80S sub woofer. I would like to add one more mission 8 ohn speaker to each channel, wired in parallel. The rating on the back of the TEAC is 6 ohms. I would like to know if I`m going to blow anything up. Any advice would be much appreciated.
