I have my sub crossed over at 60 hz and still seem to get some bad overlap onto my front speakers. What does everyone else have theres set at. preferably people using components.

Are pulling the bass out of the front speakers? I'd try that at first but you'll lose Bass Up Front. What is your set up? I haven't really ever had a problem like that. But I listen to rock with heavy kicks and slaps so, that fronts play those and the sub reinforces extended notes.

my fronts sound like they drop about 6db an octave at 400hz or so, with a few odd peaks.

What's the frequency response of your sub??? Try setting your cross-over frequency at 100Hz and see how that works for you, then you can try adjusting your low-pass filter until you get a desired effect.

Try upping it to 90 or 100hz and overlap you doors at 80 or 90hz.

What kind of speakers are you running in the doors? My Orions perform flawlessly and hit hard midbass.

It sounds like you're trying to match the natural rolloff of your drivers in front with the crossover frequency of the sub. I hate to say it, but you'll likely never get a good result that way.

One way to easily and cleanly eliminate the overlap is to run inline high-pass filters with all your speakers. I'd recommend second-order high-pass filters crossing over at 150Hz for your front and rear speakers. You can then tune the crossover frequency of the sub to handle everything below 150hz. This way, you should be able to simply adjust the gain for your sub until everything sounds right.

well i fixed the fronts, they responded down to about 65 hz +/- a bit so now i need to set the crossovers on the amp. but it fixed the front sound stage. of course i have enough sound proofing so that if a car blew up next to me i would never hear it throught the door

In my 91 GSX, the dash speakers and door speakers are X-over at 120hz. The rears get X-over at 80hz with the sub in, and without the sub I give the rears the full range. I usually X-over the sub at 100hz, or 80hz, depending on the music. I've found that to really stage a car good, your are going to need a nice big parametric EQ. I've always wanted one, but they aren't necessary for a great sounding system.

my sound system is great. what you wanna do is cut off the regular speakers and components at about 40 hertz, or werever yours happen to start to distort. then run your subs at the lowest crossoverpoint and slowley raise the lowpass cutoff till it sounds the way you like it. if this still doesnt work you may have your gains too high. and remember, for sound quality, you shouldnt use any bass boosts, just the proper gain setting.
