One thing I have noticed, at least according to my ears, is that the bass setting is very touchy. At the mark where it sounds "okay" there's not enough bass. But when I turn it up just one increment then I have too much.
Then again, I'm one of those who always has a dedicated bass knob on my dash to control the sub level and I'm constantly turning it up and down depending on the song. In fact, the closer the bass knob is to my right hand where it rests on the shifter the better.
I've ordered a JL Audio HD600/4 amp, and I already have the HD-RLC bass controller to go with it. I also have all the wiring I need to do the job. The only thing I'm waiting for is the official release of the LCQ-1.
