Connecting Speakers
1. Locate and mount all speakers in accordance with the floor plan drawing for
this installation.
2. Connect each speaker to the appropriate home run or speaker-to-speaker wiring
scheme as shown on the wiring plan (see Figure 10).
3. Test speaker wiring for short circuits.
Measure the resistance of each home run wire run with an ohmmeter. Any pair
indicating a value of less than 15 ohms must be rechecked for possible shorted
wiring or speakers. Correct any problems and retest.
