nemesis audio

I have two Nemesis Audio speakers (NA-65MR) and I was wondering if I could place a frequency eliminator that skar sells to cut out those low frequencies, my radio doesn’t have a crossover nor do I have one wired in. Any help would be appreciated! EDIT: Thank y’all for all the answers it has...

I am looking for some help with my settings. I am having trouble because I don't have any equipment to test the watts or amps. Currently, I have this settup: 2 - Audio Pipe TXX-BD2-15 15" subwoofers 1200RMS 1 - 32 hz ported enclosure 1 - Nemesis Audio Na-basspro Bass Processor 1 - Hifonics...
