Confused Girl

I've been on the internet forever trying to find some way to figure out how to get my settings right for my amp & subs.  I'm an extremely confused girl that really doesn't know much about car electronics so any help would be appreciated. I have the following in a 99 Grand Am:

240W Stereo Amplifier, Alpine CD Player, and 12" subs

I don't know what to set all the freqency & boost levels to... Please guys! Any Help!

I wouldn't even know if I had a filter on my amp.  I had it installed for me at the place I bought it.  The amp is Acoustic 241 SE... The subs are "Concept"... The box one big closed one & I listen to rap & rock generally. 

Ok, on the side of the amp there should be settings. More than likely there will be a filter setting (LPF and HPF and FULL) for settings, and there will be a setting called gain. I would not recommend having that all the way up. i would have that set to about 1/2 the way up. Secondly, i dont normally use the bass boost, but if you like the way it sounds with it on, experiment and see what sounds good. If there is a frequency setting, have it set to play music under 60-70 hz. This will be the outer range of most rap songs. The Filter should be set at LPF to filter out all the vocals and higher ranges requenceies.

Thank you so much but one more thing!  What do I do about my settings on my CD player.  The bandwidth for bass and treble?  And what frequency do I set the treble at?

Thanks!

Alpine CDA-9807 if that means anything?

Well on that model there is a subwoofer level. That is like a gain for the subs, sort of like the one on the amp itself. You can adjust that. I believe it goes from 0-15, i'd keep it around 10. The midrange should be anywhere from 70 hz to 2 k.hz. The treble should be anything about 2k.hz. Idont know if any of that helps, but theres what i have to offer.
