I finaly know what I want as far as my system goes.
I'll have two infinity kappa perfect 10" subs (powered by a quality class D amp rated at around 700-800wrms); CDT CL-61 6.5" component speakers in the front powered by a bridged 4 channel sony x-plod amp (75wrms/channel).
My question is where should I set my crossovers, both on the HU and the amps?
My HU is an Apline CDM-9801.
I don't know how steep the crossovers are in the HU or in the amps, but wouldn't it be better to set them all to the same setting?
One guy (from crutchfield) told me that I wouldn't hear the difference between 80HZ and 120HZ, but I definitely can hear the difference when I toggle between the two with my HU.

Strange that crutchfield told you that.. The human ear recognizes a difference of 2-3Hz below 200Hz. Now when you get up into KHz, I doubt you can tell a difference between let's say 19940Hz and 20000Hz. But that is a little different than what we are talking about. To me there is a big difference between LPF settings of 120 and 80.
Not all crossovers or HUs will filter all of the signals at a certain LPF frequency. So yes it is ideal to set them the same.

Thanks,
Now should I just play with the crossover points, or is it better to use 80hz and up with the 6.5s, or 120 and up with the 6.5s?
Both the subs and the 6.5s can handle those frequencies, so I was thinking that I might want the 80hz-120hz to come from the front.
I'm very indecisive and tend to change my mind a lot, that's why I like to leach off of other's oppinions. HAPPY

Go with 80 Hz on your LPF for the subs and also use 80 Hz for your HPF crossover to Comps.
You can experiment a bit using amp filters or HU filters, but only need one or the other... not both.
That guy at Crutch, he may be more into HT than car audio and 120 Hz is a common cross point for HT subs. But not good for car audio. Too muddy, poor definition and too much Midbass at 120 Hz.
