Front Speakers- Front High Pass Filter:

Through,30,40,50,60,70,80,90,100,120,
150,180,220,250(Hz)

Slope: Front High Pass Slope: -6,-12,-18,-24db/Oct





Rear Speakers- Rear High Pass Filter:

Through,30,40,50,60,70,80,90,100,120,
150,180,220,250(Hz)

Slope: Front High Pass Slope: -6,-12,-18,-24db/Oct

There isn't a carved in stone answer to your question; as your installation will have unique qualities which will factor into what is right for you. As an example, some component mids can play much lower than other component mids, based on size, manufacturer, model, etc .



It would behoove you to allow the speaker to play as much low information as possible without damage or distortion. This will keep the sound stage as up front as possible. If you have the fronts and rears set, and lack midbass punch, allow the sub to play a little higher to fill in for the mids; keeping in mind again for how the sub effects the overall sound.



Steeper slopes (higher numerically) will allow you to extend the frequency closer to the edge of what sound right to you. As en example, if your front mids start to sound nasty at 100hz with a -12dB slope due to your speakers having a hard time playing tones below 60hz, you could push the crossover frequency lower to, say possibly 70-80hz, if you used a -24dB slope before sounding nasty because any 60hz information would be cut more steeply (quieter) with the -24dB slope.



Messing with the sub's phase can help to make your system sound more cohesive by putting the subs back into phase with the front speakers; my suggestion is messing with the phase while listening something that doesn't have constant bass tones such as rap music. Phasing issues are hard to detect when the tones are constant.

not sure what they call them but if your looking to kill the bass coming from your speakers only they sell a small set of wires that have a small type cerramic piece in each one ,you hook these in the power side of each speaker close to the speaker itself and they are made to kill the bass coming from that speaker and they have different sizes for each size speaker up to a 6x9.forgot the name but any audio installer will know what im talking about.there very cheap to buy.what your talking about should not even come into play.just remember this whatever side you run the power line for the amplifier,route the RCA cable or cables on the other side of the car.if the RCA cable or cables are to close to that power line you will be picking up feedback or distortion in the speakers themselves.and good RCA cable or cables are a must.hope this helps you out.
