Helping a friend fix his messed up audio distribution. Previous owner had run a combination of cheap speaker wire spiced to lamp cord from speaker B on receiver to speaker selector to 2 volume controls in other areas. If that wasn't bad enough, in the basement they spliced the 2 feeds to 1 feed before it disappeared into the addition (no access). Needless to say, the sound was less than stellar, and barely audible!
To correct this, I advised him to purchase a surround receiver with 2nd zone audio output. I ran an rca cable from 2nd zone output to Sonamp 260. From the Sonamp I ran speaker wire to existing Phoenix gold speaker selector box. Finally yesterday, I bypassed the wire from the speaker selector to the volume controls. I replaced it with in-wall 16 ga. 4C wire. The sound was marginally better.
I am at a loss as to what the problem is, I was confident the spliced inferior wire was the main problem. Thinking maybe the volume controls are an issue...found no brand on them, wondering if they might be impedance matching, and so is the speaker selector (the selector has protection switch), maybe they are 30 watt volume controls?
Any thoughts or ideas would be appreciated!
