lots of decks let you turn it off....both my Alpine 9835 and 9887 allowed to turn off all amps and internal processors

Go to page 35 in your manual.

According to your manual you have to enter the stand by mode menu... Not sure how to do that on your unit, but its in there.

if your using amps, you don't need the head unit to amp anything. why have the internal amp on if you don't use it?

I run my 880 as a dead head... No reason for it to be running.

i had a kenwood that gave me the option to turn the internal amp off.. i had to turn the headunit off, with the ignition still engaged mind u.. basically so u can still see the clock.. then held "menu" or "audio" for a few seconds.. can't recall exactly.. but it was the same drop down menu as selecting the speaker sizes... and scrolled down until it had the option "internal amp on/off"...

i know u can turn the sub off by holding down on the right control knob/stick thing

Not all of us are lucky enough to have a Dennford. :crap:

It's a great Headunit. I wish Rockford would spend the time and effort on head units and eq's again. The Rockford 8250 and the Symmetry II are still some of the best pieces of equipment out there.

Nope, for the 9887 (I own this HU) you either set Power IC to on or off.
