I need some help tuning my head unit. B 4 i got this unit I had some boston pros with a stock honda s2k unit. I had an jl 300/2 powering them. They sounded great with the stock unit with lots of bass that I wanted. But after the install in the new unit all the bass went away ? I want to know how to equalize my unit??? I see stuff like 60hz etc.......but dont know which one to move to get more bass?? Any one know which one to move???? Thanks, I know im a newb!
