Default Perfect phone but bluetooth streaming sucks.

Is there a file that we could modify to up the quality of the streaming audio? I remember on my nexus 4 running jelly bean I had to mod a file to fix the same problem. This is the only problem I'm having with this phone. I'm in my car for a long period of time throughout the day and im tired of the highs crackling and muddy bass. So if someone could give a helping hand it would be much appreciated. Thanks
