[Rickygonzalez]

Can tip PayPal or send money from a different platform if needed. I am locked out of cash app though… looking for as close to 7 cubes as possible tuned to 33hz. Double 3/4” with bracing/dowel rods. 

Vehicle: 2023 jeep compass trunk
Sub: Fi HC 18d2

Amp: Salt 2k 1ohm

Electrical: Big 3, (2) Xs D950, stock alt

Sub up, port back on passenger side of vehicle

 

Max space available
Width 35”

Height 19”

Depth 21”

7 cubes net not possible on those dimensions, I am sure you can go wider and taller in that vehicle, preliminary calculations shoe a maximum of 5 cubic feet net is possible for a double layer box and about 6 net for a single layer with double layer baffle is possible (heavy bracing).

They added this plastic piece on interior for 22+ model that interferes starting at 17” height if width exceeds 35.5” can’t squeeze any more out of it. 35” width clears it though. Single layer double baffle around 6 would be great. Thank you!

So here is a suggestion, power: to sub rated, amp subsonic filter to 28Hz, minimum port clearance 4 1/4", figure is just an assembly guide:
