Guys please don't recommend a cap..
those are very inefficient ways to tackle the problem.
OP you need to invest in a Stinger cell battery or equivalent mods if you're having draw issues. Alternatively, one can invest in a deep cycle battery but I've never had great success running the Optima blues- their QC is terrible. Perhaps it has changed over the years.. There's a reason why serious enthusiast/comp car audio builds are using seperate cell batteries to help with draw.
How are your grounds? Where did you ground the amp to? Those play in huge to proper audio circuitry and if the ground is shitty, your current management will be shitty.
I will agree that the compression from current gen Bluetooth 3.0 and 4.0 aren't better than lossless or even full 320kbps 44 tracks but it does help to distinguish the difference between early Bluetooth technology (BT 1.0-2.X), and current tech.
Iphone 5 I believe was the first to offer Bluetooth 4. I strongly suggest A-Bing the SAME track on USB, cd, and BT 4.0. I stake that a vast majority couldn't tell the difference.. that's a test that requires a bit of a large sample, but would be easily replicated and procedural.. able to be re-tested.. all the requirements to a good empirical trial
