Recently I became the owner of this Volvo XC 90
. The first what i saw the bad sound quality :crying:
so decided to cheche the AMP to pioneer GM-A6704 its 1000 vatt but the main problem is the original head unit cant support that AMP so the solution is change thehead unit
to android but I HAVE TO INSTALL THE AUX How come? The unit is install but NOT sound who knows how to install?
