Mono Amplifier - Strapping the Ouputs
MASTER
AMPLIFIER
SLAVE
AMPLIFIER
• Connect the master amplifier's speaker output + terminal to the + (positive)
terminal of the woofer
• Connect the slave amplifier's speaker output + terminal to the - (negative) terminal
of the woofer
• Connect the two amplifier's speaker output - (negative) terminals together
You are creating a much more powerful amplifier in this way and doubling the output.
Make sure your speaker wire can transfer the power, we recommend a minimum of 12
gauge speaker lead, and for best performances you should use 10 or 8 gauge.
