Right, probably not the right section but! but! I have put my alpine headunit in the glovebox (in place of a cd changer) and put a Galaxy Tab 3 in the dash! So ... the idea is with alpine headunit I usually listened to music on volume 15 from a CD or USB stick... with Tablet connecting i have to turn up volume to 30 for comfortable sound, although i can hear that "Radio Wave" sound because volume is way too high on the headunit. I remember on a kenwood headunit i used to be able to set AUX gain, which meant i could comfy listen to audio from AUX on the same volume as from CD without any distortion. Now then... alpine headunits got another thing, u can buy AUX+ cable which goes at the back of the headunit and u just connect it to any phone, tablet whatever. The question is will AUX+ give better sound? be louder on lower volumes? and whats a real difference between AUX and AUX+?
