Parts Express 80 Hz Low Pass 8 Ohm Crossover
If I use this crossover with a 4 ohm subwoofer, can I assume the crossover point would change to 40z? And would the slope remain 12db/oct?
yes, The crossover point would "half" in a low pass.

if I need this to handle more power, can I wire 2 of these in series, between the amplifier and an 8 ohm subwoofer? If wiring it this way is acceptable, what version of this crossover (4ohm or 8ohm) will be compatible with my 8ohm subwoofer?
Wiring two of these will change the crossover frequency. If you want higher powered crossovers you will have to swap the components on these boards with higher powered options.

I have drivers rated at 4 ohms impedance. Can this crossover be modified to function properly with this impedance rather than the 8 ohms design parameter?
In order for this to work at the same frequency with a 4 ohm load the component values will have to both be changed. You would be farther ahead buying the 4 ohm version of this filter which you can see below.http://www.parts-express.com/parts-express-80-hz-low-pass-4-ohm-crossover--266-440

ok,got the answer!.so I Am Looking For A 500 Watt Version of this Trying to do this right!!. can you tell me were I may find one?.
We do not have any higher powered low pass filters at this frequency available. We do have a couple at 250 Hz that handle about 600 watts, but those are the only options we have.

Have A 750 Watt 18"inch Sub can i use this with this sub ?. Have A Cabinet Maker friend of mine Building (186)Horns "Modified".I'm New to this but i'm willing to learn.what i want is to cut down on the hi side just a little.so is this crossover good.
This will work but you will be limited with the amount of input power you can feed it. This low pass filter is limited to 250 watts RMS, anything more than that and it will start to heat up and the components may fail.

I'd asked about using this inline to an *" subwoofer and Matt said not recommended and that I should replace the amplifier. I assume Matt was talking about a new plate amplifier? If so, there is a 50W and a 100W on your site that could work?
We have two models that will work well. The Dayton SA70 or SA100 will work fine for this application, as well as the Yung SD100.
