I have an issue with my m4 aqua. when its connected in the car with a 3.5mm jack it seems that i can t have the full sound i have to put my car radio at max to have a acceptable volume. and my cell phone volume is at max. Can someone help me with that cause i really cant find a solution to this. I tried with my old htc 1s n the sound was really lower on my sony m4. Is there a setting that i can change or is it something else...
