I've got 3 speakers on the left channel, and 3 on the right channel plus one subwoofer, 7 speakers total. All 6 ohms. I used to be able to have the stereo on max and it would sound fine (max is 64) but I can't even have it up to 40 without the left channel going in and out. I checked all the wires and nothing is interfering with anything... if anyone can help it would be greatly appreciated!
