Swapped my gf's 10w6's for a 13w7 but the box it was in won't fit in her trunk so now I get to build a new one. No loss as it was just a prefab anyways. I have been researching for the past few days but answers are all over the place so I thought I would see if anyone is kind enough to provide some specific advice. Jl recommends 2.375 net tuned to 30 hz but it is my understanding a higher tuning frequency gets louder and low to mid 30's is a good compromise. Also that jl undersizes there boxes and the 13w7 specifically models well in a larger box she wants to get every bit of output she can out of it with keeping it musical/ sounding good so basically sql although I know some of you dont like that term. Reason she ditched the 10's was they didn't get loud enough although they sounded great (10w6v2 sealed @ 1 cube each gross)

Placement behind rear seats facing forward (she prefers it that way) will probably try a "baffle" to experiment with stopping reflection cancelation
Box size due to the small trunk lid it's hard to fit a tall box (problem with the old one) so limited to about 15 tall preferably 14.5 to be safe width about 27.5 depth can be what ever is needed

Power currently a jl audio hd1200.1 but it has no subsonic so I will have to figure something out for that.
Would love to hear all your thoughts/recommendations this will be the first box I build but I'm not new to woodworking. I also have winisd and even though I'm new to it and still learning I'm going to come up with my own ideas and see how it compares to what you all think.
