I'm going to be running a pair of focal polyglass 6.5" components up front off my zapco 4chnl and am debating putting another set of the same in the rear deck.

I currently have just normal pioneer 3 way 6x9's back there.

I'm debating just running those 6x9's off the deck just for fill, run the focals up front off the amp and then have my IDQ 12 running for bass.

So what should I do, run the 6x9's just for fill, or get another set of the focal components?

Thanks

Run the focals active and leave the rear alone IMO.

So don't run any speakers from the rear, other than the sub of course?

That is my opinion.

Thanks, I was considering that as well. I'll give that a try.
