800 Hz Low Pass 8 Ohm Crossover
How would you recommend mounting this for a car audio application? They will be on my rear shelf (metal with fabric panel overtop.). Thanks
The easiest way would be to wrap cable ties around them since they don't have mounting holes. Velcro or strong double sided tape is another option, although a hot car will probably cause the adhesive to fail eventually.

Would this work on a 4ohm speaker?? I need to cross-over at around 400-500hz but you do not have a 4ohm available to crossover at that freq.??? I would build my own but do not know what size coils or resistors to use??
It will work with a 4 ohm driver but it will not cut the crossover frequency in half. I would recommend a 60 uF cap and 2.5 mH coil for a low pass at 400 Hz using a 4 ohm driver.

I have a goldwood GW-s525/8. It is an 8 ohm speaker but when using this low pass filter I can still reach over 4khz. How can I stop this? Or am I doing something wrong?
At 800Hz crossover, a 12 db. per octave roll off you will get minus 12 db at 1600 hz [about a notch below half volume]. At 3200 Hz you will get minus you get minus 24 db [about one quarter volume] At 6400 Hz you get minus 36 db [about one eighth volume]. So, a roll off filter does not eliminate the signal, it reduces it at it's the specified rate. This is to give you a smooth transition from bass to mid/tweet.You can still hear the 4khz at that rate. Now this is assuming that your inputs and outputs are correct. I have been known to reverse them. OOPS!

I want to 3D-print a Speaker Wire Terminal Plate and incorporate a mount for this x-over. Does anyone know the PCB dimentions of this x-over ?
I have ordered one but I would like to start on the build before it arrives.
The PCB measures 4-3/4" L x1-7/8" W.

does the x over show which side is in and what is out to the woofer
Yes the board is labeled to show which is which.

mounting inside cabinet
I don't see any screw holes so how do you recommend mounting it? If glue what kind?
You can drill through the board. I would put two holes somewhere around the large inductor. As long are you are mounting into wood or something none conductive, you should not have a problem with shorts from your mounting screws. If you are worried, make the hole have generous clearance from your screw and pick up some plastic washers. Then again, start with a bit larger than your screw head to remove the metal clad, then finish the hole with something a little larger than your thread diameter.I have mounted crossovers with hot glue (only on flat horizontal surfaces) and epoxy (mix it up) type glue on sides or the top.I have also fabricated a board to hold the crossover with scrap, cable ties, and hot glue, and then mounted the board to my box.I hope this helps and best of luck with your install.
