As Exad has asked, Boom Bass will not work with GPE. I got one free with my phone. I converted back to sense to try it, for what it is it sounds pretty good.
But when I went back to GPE - nothing from the phone and just muffled thudding from the boom bass.
Put on a Sense rom and it will work perfectly
Lol couldn't wait for him to answer and thus robbing me of solving the issue! I will exact my revenge!
