I know this question has been asked a million times, and yes I did search the website looking for advice. I found lots of people saying 80hz is standard for subs, but what about components?

I was guessing that if I set my subs to 80 then my components should be in that area as well... Is a small amount of overlap a good thing for smooth transition?

Also what about the frequency on the HU, I was told that this should match whatever was set on the amp, makes sense to me, but the guys that told me this also hooked up my ground wire, which eventually melted its way through my trunk...So i thought I should double check

Any advice on what to set both crossovers to is greatly appreciated!!

I think it will boil down to what speakers you have and what their locations are. My last car has the sub set from 40Hz @24db per ocatave down. And my midbass speaker were bandpassed from just under 40Hz to 200Hz. But that was my car. If you have active crossovers, find the best compromise between power handeling and sound (for daily driving that is).

I have Hertz ESK 130 5.25" component speakers up front, and Clarion Coaxial 6.5" in rear, both powered by a Clarion APX4240 amp (60 watts per channel). If it matter at all my tweeters are VERY bright and somewhat annoying, but I think I'm stuck with that, at least I can half assed tune them down on my HU.

I don't really know anything about crossovers, so I don't know if its active or passive, all I know is its built into the amp, and has LPF or HPF, no bandpass.

Trial and error, buddy. Every car is different and every set is different. I have my components highpassed at 80hz/12db and sub at 40hz/12db off the head unit. In another car, components are crossed at 80hz/12db and sub at 80hz/24db

I'm so glad I saved this as a text file.....

This process is a lot easier to do with 2 people....you will also need a source for the cleanest music you know well....ie. original CD....anything ripped and saved as MP3 or WMA may suffer some loss of quality during the conversion process.

In as few words as possible.....

1. Check deck and amps, ensure all boost, EQ and gains are set to minimum.

2. Plug in RCA for front R speaker only. For 5.25" HP starts at 120hz, either in deck(preferable) or on amp. Using music you know well, raise volume on deck until it starts to clip, back it off till distortion is gone. Raise gain on amp very slowly until distortion is heard again, back it off. Lower volume on deck, lower HP setting 1 step (or approx. 100hz if variable). Repeat this process until you find the setting that gets you the most volume without distortion.

3. Repeat process for front L.....if you are using rear speakers I usually leave them out of the process until later.

At this point you have as much sound from the front end as the equipment can handle.

4. Plug in sub RCAs.....set Xover at approx. same value as HP minus 20 hz. Unplug front RCAs, raise volume at deck until distortion is heard, back it off until distortion stops. Try raising gain to see if there is any headroom left in amp, after fiddling, sub should be getting as much clean power as possible.

5. Hook fronts back up, listen to system at moderate volume....listen for even volume across all freq. If you have a test disc it will help with this part. Try adjusting sub gain and Xover to help the mix if possible, having set the fronts to their maximum output it is generally better to try and match the sub output to that level rather than the other way around.

6. Once you have found the best sounding (to your ears) settings, then hook up your rears. If you have a 4 channel running the mids and highs, unplug the fronts and the subs and repeat the setting process you did for the fronts.

7 Plug them all back in.....at this point you should only have to adjust the fader or the gain for the rears to get them to blend with the other speakers until you are happy with the sound.....

Setting the subsonic ( or infrasonic if ya wanna pic nits..... ) just below Fb is a good way to keep the woofer(s) happy.....it's all about getting the most you can out of what you have.....
