We don't have near enough info to be able to help you. What size front and rear speakers do you have, how much power are they getting? What size woofer, and how much power is it getting? Even with that information all we can do is give you a safe setting so you will not damage speakers, you will have to decide what sounds best to you.
I personally run my system at 80 and down for the subs and 80 and above for the fronts and rears.

Agreed... Sub only or full system? Door system amplified (meaning a dedicated amplifier, and not deck power)? Vented or sealed subwoofer?

Otherwise, my crossovers in my car are thus:

Sub - 65Hz and down
Bass - 65Hz to 250Hz
Mids - 250Hz to 3.5kHz
Tweeters - 3.5kHz and up

Those will very likely NOT work for you, but this simply gives you an idea of what we need to answer your question better.

Additionally, if you are using your deck for powering your highs, then the crossover will do you zero good, all you'll be able to use it for is the sub control.

It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

I'd have to guess that there is not a single piece of Performance Teknique equipment in that setup.

Uhhh... Your guess'd be right on the money. My remote lead cost more than that crossover.
