help me properly set up my new system!

[gonoles92 10+ year member]

hey guys, so I just installed a new amp, speakers and sub and don't know exactly how I should set it up (I'm a noob). I've got a pair of Infinity 6032si in the front doors and a rockford P1s412 in the back, both are powered by a 4 channel 400 watt RE Audio amp. My head unit is the JVC KDHDR60 which has a built in 3 way LPF, I can choose from 72hz, 111 hz, or 157 hz, it cannot be turned off.

My question is should I use both LPF's and if so, where should they be set? Currently I have my amp's LPF set to "flat" with the HU's LPF set to 111. Just curious what you guys think is going to give me the best sound. I listen to alot of hiphop/rap and classic rock.

LPF needs to be set around 80-100hz.

alright, so should I set the LPF on my HU to the high setting (157 hz) and the one on the amp to somewhere around 80-100hz to filter out what's sent from the head unit since I can't turn the HU LPf off?

I'd set the amp LPF to around 90hz. I wanna say set the deck to the lowest LPF, but thats 72 in this situation? JVC really does like to make things **** lol. I'd say low to break it in but you might as well set it to the mid range 111Hz. I don't know what those mid range drivers are but if you have a HPF on the amp for them you should try to cover the range you're getting up to on ur subs 111Hz, if the mids can handle that cranked to however high you'd crank it without distortion then set it to that. If they are distorting, back it off to like 120-135hz untill they don't distort when you crank them. Then you have ur full range covered and you're not sending too high of frequencies to you're subs. You could try the LPF on you're Deck at 157hz but that starts to worry me thats a little too high of frequencies for subwoofers.
