Isn't that redundant? I have a Pioneer DEH-780 HU with internal x-overs and slope adjustments. Do I need to use the x-over at the Alpine PDX 4.150 amp as well?

No

It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

"No" to which question? If I'm reading you right; which x-over would you use? Thanks bud!

Yes, redundant. No, amp crossover not needed, use the far more flexible on built into the head unit..

Thanks for the quick reply. This was my thinking too, but I've been out of this hobby for years.
