I solved my weak low volume using Medlez new build for Noozxoide EIZO. It works fine. See Nexus 4 Forum.
Also VLC did wonders before I installed it. So Vlc is your best bet if you are not rooted. Other players with volume gain feature like Diceplayer and Archos raise video volume but not as much as they did on my Galaxy. I couldn't hear anything in the car.
With EIZO vlc is now too loud and reaches distortion level easily.
Hope this help.
