Run amp to rears to keep HU amp off?

[Motovet 10+ year member]

I have some Germs coming, and will probably run a Zed Duece on those. I am getting the new Pio 880PRS, and I see that the internal amp can be shut off completely. So I had planned on running some Rainbow SL coax's in the rear off the HU as they will only see duty when passengers are in the back seat.

Question is...is it beneficial enough to keep the HU amp off at all times and run a low watt amp for the back,(75Wx2). Or stick with the HU power for fill and maybe get the Burr Brown upgrade for the Germs?//content.invisioncic.com/y282845/emoticons/eyebrow.gif.fe2c18d8720fe8c7eaed347b21ea05a5.gif

Since you wont notice a difference id just run the rears off the h/u

Theoretically, if the HU's amp is off then the voltage of the HU to your RCA cable increases. Which means more voltage to your amp and a louder output. You won't hear the difference but if your runnning your speakers to a seperate amp, there's no point of having the HU's amp on, in my opinion.

Doubt it. If there is no load, it will draw very little current.

maybe 1-2 deg...
