Car Audio Forumz - The #1 Car Audio Forum - Pioneer amp dx975 set up settings

Hi all,
Looking for some advice here as I haven't done this in a while. I've installed polk speakers 6.5 - db6502 components frequency rangen 35Hz-22kHz in the front of my 2018 hyundai kona and the polk 652's frequency range of 40Hz-22kHz in the back (all rated 100 watts @4 ohms and I've also purchased a Kicker sub 10" CompC 44TCWC104 frequency range of 30-500 Hz which has a rating of 300-350 watts rms. Now I'm installing pioneer dx975 which has a rating of 4x75 watts rms 4 ohms and sub @ 300 watts at 4 ohms. This is going to be hook up to my factory radio via the speaker input terminal on the amp, so what would I set up my crossovers at for the sub and speakers and what tones should I use when I'm setting them up ( I'll be using a oscilloscope) . Appreciate any advice, have a great day!
