Is there a place on the back of P 10 to attach ground cable?

Subwoofer size and connectivity

It’s pretty simple really. Just get a second set of inexpensive speaker cables and connect both sets of positive and negative connectors on the sub end. On the amp end connect just the positives to the amp and the negatives to an alternate grounding point. I used the grounding post on a Line conditioner.

Hey dawkinsj, I am trying to do this. Just haven’t been able to find a place to attach the ground.
