Makes a big difference in sound clarity. Hotter signal to amps means lower gain and clean sound.
I'm running Boston SPZ60's in my front doors, old Boston Pro's in the rears, both driven by Rockford 801x amp. Rockford 10" p3d4 Sub in sealed .5 box driven by alpine PDR-M65. Kenwood Excelon Head Unit, and Audio Control Three.2 being used on sub input only. The Matrix is easy to hook up. The manual says put it close to the head unit but size makes that hard so it put in under my front seat right next to the alpine amp. I called Audiocontrol 1st and they said in a perfect world it would be close to the head unit but in reality anywhere is fine. It made a noticeable difference in sound clarity and quality and allows me to keep my amp gains low by sending stronger voltage than the head unit will. The Kenwood says it's 5V. That may be true right at the unit at full volume but I measured volts at the end of 10 ft RCAs with volume at 27 and it's only about .75 volts on the fronts and rears and .95 on the sub output. The mids are very clear and can go loud with no distortion or ear fatigue. The sub is very smooth and clean and the kick gives me a back massage. The really low frequencies feel like a wave coming through the entire vehicle, instead of just vibration. Amp gains? Fronts and the sub-barely turned up, less than 1/4 of the way and the rears the amp gain is all the way down. Very happy with this unit.
