Can't get this to work, what am i doing wrong.

[Boof150]

So i was messing around with my truck today and was trying to wire up a Selenium D250-X and had it hooked up to this JL 4300 amp i had laying around. The speaker is brand new and i know the amp works because i have used it on and off again for different setups in the past. I first tried wiring the selenium up bridged between channel 1 and channel 2 to see if it would play sound and what i got was mostly static/whine and the speaker trying to play bass notes. I messed around with the filter settings on the amp and on my head unit but i was unable to get the selenium to play anything other than static/whine and very quiet vocals. Is this a crossover problem or is this amp and speaker combo not compatible?

I found these pictures from another user on these forums of the amp in question.

Prolly not a matching issue. Try a different amp......

Playing around with the speaker i have come to the conclusion that this is a crossover issue. Setting the headunit and amp to filter at 200hz, which is the highest i can set them, i get the most sound out of the selenium. My question now is how do i go about increasing the crossover point to the speaker's correct range. Is this something i can do on the headunit and amp or do i need to set the crossover before the signal reaches the amp?

Get a separate tweeter crossover or any 2 way passive crossover. It definitely sounds like the filter is too low. Check on partsexpress

What my concern is now is that the headunit seems to have no setting to turn off it's filter, i only have the option to toggle between numbers between 50-200hz. Would getting a seperate crossover eliminate this issue or would the head unit still only send frequencies up to 200hz to the new crossover?
