trying to get louder 28-100Hz, which 8's? 2 Kicker S8L7s vs 2 Sundown SA-8s

Just moved my HPF to 80Hz and it dose sound alot better. Now with the 4 6.5's plus the sub playing the 80hz tone its at a decent output now. Although i did notice that if i used my HPF on my HU it canceled out the HPF on my amp. No matter where i set my amps HPF the 80hz tone played with the HPF set to 80Hz on my HU. Weird i thought

Turn your crossovers on your amp to full and tune from the headunit to prevent that.

okay thanks, ill switch it over to full

O and i was playing some test tones, and noticed that the 47Hz Fq still moves some air outa my box, along with 50Hz. So how come the higher bass in my music dosnt play loud?

shape of the response curve of the enclosure coupled with the vehicle's cabin acoustics. Also has to do with box rise, the woofer is going to play at a set ohm level, each different frequency will make the woofer play at a different ohm level. You could be getting a higher rise towards the top, which will cut down on the amount of power that the woofer sees.

So to counter act this i would?????? Im guessing a new box design would be needed, but wondering what would need to be changed
