So if I listening it like 40-50% loud, it's good. But when I turning it louder, just the mid and high speakers gets louder. I have a jbl amp with 300-400 rms watt with same watt sub. I tried it with much stronger setup but it did the same thing. In lower and mid ranges was stronger but when I get higher ranges the sub stuck in 50-60% ranges. Please help!

Before anyone is going to be able to help you, you'll need to provide more specifics of what you installed and how you installed it. The HK system is a canbus (fiber) connected system, so the factory amp will only work in a BMW. What did you change? How did you wire it?
