Solution
For practical purposes a dedicated sub amp is a mono amp, and you have a stereo amp, so just use one channel, unless your amp is capable of bridging.

thanks of the reply, understand that, but my amplifier only have left right input, don't have sub-in jack input, just need to know what type of cable do i need to connect into left right input(red and white)
