I'm trying to help my friend get his wall working properly and he has a total of 12 speakers to run on 4 Channels. Thats 3 speakers per channel. Need help find the best way to wire these getting them as close to 2 Ohms but not below. If need be we can do 4 Speakers per channel over 3 Channels and use the 4th channel for tweeters. If this can't be done please inform me of better way to set this up thanks.
