The sub are Alpine SWR-1242D the app is a kenwood KAC-8104D class D mono block. Her car is a 05 Nissan Alton's. The dimension are w=24in L=17in H=15.5in if u can help me with this sub that would be great. And if it possible to build those maze slot ported

Here is a suggestion (simplest port layout is more efficient), power: to sub rated, amp subsonic filter to 28Hz, minimum port clearance 2 1/4", figure is just an assembly guide:

NOTE: If building outside you need to build a cardboard dummy box to test fit in it's way inside.
