I'm not sure what the problem is with the JBL system. I have many years experience with amplification and speaker design and my JBL system sounds just like it should given the components installed, and sound controls in the head-unit are plenty to calibrate it.

But if you think your channel levels are horribly mismatched, you can easily attenuate drivers using a fixed value resistor (which would cost a few dimes) or a rheostat (which would cost a few dollars).
