Infinity Basslink LPF Crossover Question

[poopshute]

New here and hopefully this question isn't too noob...

I have heard that using the LPF on my hu AND on the amp isn't ideal (one or the other). Here's my dilemma... I want to use the LPF on my deck but there isn't a setting on the Infinity Basslink to disable the crossover. Can I simply set the crossover on the basslink to its highest level (120) and then use the LPF on my deck to set it to what I want? Or, am I stuck just using the LPF crossover on the Basslink?

I'd eyeball it around 100 and then use the deck from there.
