Wiring
70V:
Note: for ST-SUB-12 Only
Connect the red cable (70V+) and black cable (70V-) to the
amp. Make sure the white cable (70V- Output) is
connected to the blue cable (4 Ohm - input) and the green
cable (70V+ Output) is attached to the yellow cable (4
Ohm + input).
4 Ohm - ST-SUB-12:
Connect the yellow wire (4 ohm + input) & the blue wire (4
ohm - input) to the 4 ohm amp.
4 Ohm - ST-SUB-10 or RK-SUB:
Connect the (red + 4 ohm) and the (black - 4 ohm) to the
4 ohm amp

70V Tap Settings
Set taps to 80% maximum of amp’s capacity. The tap
settings can be changed as long as the total speaker
wattage does NOT exceed 80% of the amp’s power.
NOTE:
Lower tap settings allow for more speakers but a
lower maximum volume
Finding the Correct Tap Setting
AMP POWER x 80% = SAFE
500W x 80% = 400W
400W ÷ 50W = 8 Speakers
OR
400W ÷ 30W = 13 Speakers
