Well man good luck with everything. Im goin through a similar situation and from experience, you both have to make yourselves happy and if you do get back together her family will eventually realize they are missing out on your daughter's life bc of their own petty bs and will hopefully come around.
I may have missed it in your build log but what kind of power you gonna get for them bc those are crazy numbers just for 1500 rms. Can't wait to see more power.
I wish you were doing this next summer. I'd try to get three of those autographed 4000's for my big build.
edit: just saw your post about not selling anything,,,
Idk if the place you found is an authorized dealer or not but this site is and they're about the same price.

Hope it helps.
Thats the best price you're gonna find on that amp and you won't beat the amp or the subs pricing from an authorized dealer. Not a big fan of audiobahn. If I was to ever go back mainstream it would be kicker or rockford.
