I have 3 JL W0 10's in a sealed box running off of a 250/1 JL AMP. I also have an eclipse CD 3422 HU. Now I know JL isn't highly regarded around here but it was what my insurance company stuck me with after my old system was completely stolen. My question is that I've had them almost 10 months now and I've never been very happy with the lows. The HU is great but I never get alot of bass. I took my first look at the setup today and my amp had it's LF (low-frequency boost) at 0, should I turn this up? I don't want to F anything up so I'll take it slowly.
