Need Some Help With My Panasonic Cd-player

[Justy311]

I need some help with this. I have a portion I know absolutely nothing about, and figure maybe some of you eletronic geniuses might be able to help me. I have included a picture of what I need help with, if any help can be given, please let me know what this means!

pretty much u set how much bass you want coming through your sub(low pass) and your in car speakers (high pass)

pretty much for high pass for a factory setup anything over 120 is good

and for low pass thats all on you depending how high freq sounds you want your sub pushing out

[Justy311]

So if I put the low pass as low as it goes, the lower the bass that will be allowed through? So with the speakers which is best? I have an aftermarket system, but not sure what will sound best, since I know nothing about these different Hz. Thanks for the response!

First you need to understand the frequency range. Normaly 20,000 down to 30. 20,000 to to around 2,500 are in the tweeter range. Around 2,500 down to 200 is the midrange. 200 to 100 is more of a midbass. 100 down to 30 is bass. And below 30 is subsonic and could damage subwoofers. There isn't a exact setting because some speakers will be able to handle a broader range. Your front and rear speakers will use the high pass filter to allow higher frequencies to be heard. 200 is the norm set point but your aftermarket speakers could probably go down to 140- 100 with good response. Your sub filter is the low pass and allows lower frequencies to be heard. I would start with 200 and go down. Most likely your sub will sound better around 100htz. Be sure to play rock music while listening to this. The 100-200 range is midbass like a guitar or drum beat. If your guitar sounds muddy (most spl subs do in this range) then lower your setting. If your HU has a slope or db setting then try a 12-24. The slope how many frequencies beyond your crossover setpoint are heard. The lower the number the higer the slope. Meaning that a 12db slope will allow more frequencies to pass than a 24db slope.

Amazing, that makes so much sense. I appreciate the help on this one mikegett. Thanks again!
