Internal Amplifier on SQ/Alpine 9835 wiring help

First off,
I have just received an alpine 9835 and was thinking about running my rears off of the deck and my comps off of the 3 way (with amps). I was wondering if there would be a great deal of SQ difference with the alpine internal amp on or off (if there is im just going to just sacrifice the rears).

Second off,
It says that for the 9835 there needs to be a 10 ga wiring to the battery (for the v-link internal amp). The deck i have right now has a higher gauge wiring, i was wondering if i could just use the existing one (seeing as im only powering rear speakers) or if i should run separate wiring....

Thanks for your help guys!

first, no there won't be a drastic sq difference, however you can mess up your sound stage with rear fill. nothing wrong with trying it out.

second, i would run a seperate opwer wire to the battery. From what i hear if you don't the deck may cut out during high volume.

I am not sure about when you turn off the internal amp, but I know that on models such as the 7998 which has no internal amp the signal to noise ratio is much higher then that of H/U's with an amp.

well, you will get better sq with the internal amp off. Will most be able to hear the difference, i doubt it.

when you use the speaker outputs the alpine will run warm, and that will keep the internal fan on all the time. Thats gotta reduce SQ.

I only have 14 ga. wire on mine, but don't use the internal amp.

im gonna try it at the 14 gauge power with 2 speakers (so like 50 watts rms) and see if it handles well.....

I have an Alpine 9845.
I have a front stage amp and a sub amp connected to it.
When I first installed it, I played with turning the Power IC "ON" and "OFF"
I couldn't hear the slightest difference.

It might make a difference when the HU might start to heat up from pushing extra speakers, but in my testing it made no audible difference.

Play with it yourself, if yours is similiar to mine, flipping the power IC on and off is very easy.

I have since left the power IC "off" because I have no other speakers to run and I want to keep my HU as cool as possible.

these decks for some reason,the internal amp output winds out sooner then the rca voltage,just use the fader,i know it doesent make sense to me either lol,but it is what it is.
