Just bought a 2015 RAV4 XLE. Love everything about it, except the sound. First off, the sounds maxes out at a volume that isn't all that loud. Also the sound in general is typically swallowed up by the bass and the vocals sound faint. I've tried adjusting settings, but still no luck. In a word, I guess the sound is just uninspiring altogether. Anyone have any recommendations on how to fix this? All I need is sound that will be louder and clearer with a little more punch, nothing too crazy. Just will be listening to rock music mostly. Will replacing just the speakers take care of this? Also, are audio mods allowed on leases? Thanks.
