I just got a power acoustik 3000 watt mono amp and im running two cvr 12" briged on one chanel and cant figure out where to put the subsonic and lpf setting there in a nonported box in the trunk of a 09 impala. I keep haveing the problem of some notes hitting good and the rest just sound like crap any sugestions?

LPF should be at 80Hz, subsonic isn't exactly necessary but it's good to use. I would set your subsonic to ~20Hz.

By nonported box I'm assuming you mean a sealed box. Sealed boxes can sound a lot different from a ported box, so that may be what you're talking about.

What do you mean by sound like crap? Is the sound quality bad or is it just not loud enough? And what frequencies are hitting good and which ones are giving you problems?
