Hey guys,

I recently got a deh-p4600mp.

It has front and rear/sub preouts,

So I have the rear going to my amp for my sub and the front going to the amp for my fronts.

Now I have the rear speaker connected to the actual HU.

But now Im trying to get the 4 in car speakers to play mid to high, and i want the "rear" preout to play more of the lows, but I get the impression that my HU cant distinguish between the signal coming from the rear preout and rear high level inputs so whatever it does to one it does to the other.

Whats the best way to configure this?
