“So i have 2 70 Watt 8 ohm Woofers and i was thinking of wiring them in series so it becomes 16 ohms. How Many watts rms would 16 ohms give???”

Speakers ohms don't make amplifier watts. Not sure what you are trying to do but it sounds like noise. 8 ohm speakers use less power to drive than 4 ohm but hooking 10 8 ohm speakers together does not make an 80 ohm anything they are all still 8 ohm speakers.
Sorry, there was a problem. Please try again later.I'm not sure exactly how many watts the receiver would generate at 16 Ohms, but at 16 ohms, the speakers wouldn't sound very good. The wattage would be less at 16-Ohms than with an 8-Ohm load. If you connect two pairs in parallel, the load for two pairs of 8 Ohm speakers would have an aggregate impedance of 4 Ohms per channel, which the amp will not accommodate without possible damage. . When you're referring to two "woofers", are you suggesting that the woofers are in addition to speakers? If you are talking about one set of speakers, the total load would only be 8 Ohms per channel, which is what the receiver is designed to accommodate. The lower the impedance, the more current the speakers will draw from the amp, and the more current they draw, the better the speakers will sound (as long as they within the specs of the amplifier). I wouldn't recommend a load any less than 8 Ohms, as it could damage the amp. However, if you're connecting a supplemental pair of woofers to your main speakers, and connecting them in series, it will probably sound better without the additional woofers. If yo want an inexpensive receiver that will drive two pairs of speakers in parallel, you might check out the Yamaha RS-202. It's priced at a similar price point as the Sony you're considering. Keep in mind, however, that it's unlikely that any $150.00 receiver will blow your socks off, no matter how much wattage they claim it has..
