Following this thread with interest, this is something I need to get round to soon. Been putting up with terrible sound quality for years now!! I may just copy this setup if it works out good. Keep up the good work fella.

Replacing the wires?
Basically the way I see it is less loss in a thicker cable. "Volt drop".
My old home sound system used a thin single pair to each speaker. I changed the cross sectional area to 2.5 mm sq. It increase the volume by 50%. I put it down to a simple electrical law of resistivity of a copper cable.
R = ρ*L/A
whereR is the end-to-end resistance in Ohms. As little as possible, R = RL/A
ρ is the resistivity of the material in Ohm Metres. Copper
L is the length in metres. I did not change the length.
A is the cross sectional area in square metres Basically doubled the cross section.
My present home 11.2 Atmos system has 2 cables to each speaker and separate amps to the front three speakers.
So what I am saying is the less resistance your cable has the better. Also I had this cable and felt there was no harm in using it.
I must also add the front speakers came with some cable and it was thinner than the original wiring. I decided to use the front original wiring.
As for the rears it was an easy job to replace the existing wiring with the new and much thicker cable. With everything taken apart it was a no brainer I replace the cables.

Sorry I must add the power being driven is also a factor. The rears I have fitted are 100w rms so I future proofed the wiring on the rears as I may add an amplifier if I feel it requires a bit extra.
All cables have loss but if that loss is not causing an issue with what you use then there is no need to replace the cable.
Caution.
Test the original cable are still in a good condition if you intend to use them.
Test they are not shorting to the body or to each other. Not nice to put in new equipment only to blow the amp.

This is the so called top of the range from Alpine South Africa.
It has all the functions you will ever need.
I real life it looks nice. The display colours can be changed to any colour you wish. I am going to match it to the instrument cluster colour.Attached Files

White panel with colour preference selectable by user.
Large, Bright High Resolution Display
Alpine’s high-resolution display is big and clear for high visibility. You’ll find that it’s easier of use and makes driving safer. It occupies a large area of the front panel, giving you sharply clear text and graphics. All of the menu and music information is easier to see, and best of all it stays clear whether it’s bright or dark in the car.
Choose Your Favourite Colour
Quad Illumination is a popular feature that lets you choose four colour schemes: red, green, blue or amber. When you select one, all of the buttons change colour. Match the colour of your dashboard illumination to give your cabin interior a nice unified look.
USB at the rear of the head unit. Long cable supplied and can be positioned in and area suitable.
Also Aux input at the rear from any aux audio signal.
