So im installing my polk system and each of the 4 speakers has their own cross over. What the heck do i do with these things?!
Currently they are plugged in and "working" but i heard i need to tune them and have no idea how to start.

Btw they are hooked up to a polk momo 4 channel 975 watt amp, that is 4ohms. What is the magical number i need, so that i can hook up a volt meter and change the gain setting to what it needs to be.

THen there are all these other settings like slop and fall off what he heck do i do with these?!
THe amp has so many little nobs i am lost lol!

any and all help appreciated, and i did read the FAQ but it just talked about setting gain, and when i did the math that way (975 times 4=squar root) i came up with a number in the 60's and that seemed high but then again what do i know, thanks!

they are most likely passive crossovers? They may not have any tuning you can do to them, unless there are some jumpers inside that let you attentuate the speakers, or change the freq. at which they cutoff.

First of all, find the book to the amp. It will tell you everything you need to know about the "mystery" knobs.

As for as crossovers go---the signal coming out of you amp is called full-range, meaning it has all the frequencies the human can hear (20-20K htz). Your speakers can only reproduce, or you are able to hear from your speakers, the frequencies it is rated for. SOOOOO in order to NOT hear bass or NOT hear highs from those speakers, the crossovers basically allow some signals to pass and blocks others. This way, you do not distort your speakers.

You should have one set of signal wires going in, and one(or multiple) sets as output.

That is the basic set-up.
