Thank you. But now I have problem.
I have two set of Focal ES165 KX2 component.
One Hertz 12" sub.
One Zapco 6 channel amp.
One Zapco 4 channel amp (will order one in a day or two)
Here is my plan.
Front Focal mid and high component will take 4 channel from 6 channel amp
Rear Focal mid and high will take 4 channel from 4 channel amp
one 12" sub will bridge two channel from 6 channel amp
But my Helix DSP .2 only have 8 channel. My though was going to use DSP for Front 4 channel for mid/high. And two channel bridge to one channel for sub. So only use total of 6 channel on DSP. The rear Focal component mid/high will run RCA directly from the head unit to the amp without using DSP.
Please advise if better any better idea.
Thank you,
