As big as possible. right now you are looking at 12.5*14.5*36.5 = 3.8 gross cf. When you include port volume and sub displacement (total of ~.5cf) you get about 1.6 for each sub. 10s may be a better bet here.

I just built a 5.2ft NET ported box for a camry identical to yours. You can fit much bigger than 1.75 each in those cars. I think it is around 37 by 26 by 16? Its actually the perfect box for your app., tuned to 36hz which is what those L7's love is a tad higher tuning.

Then go with 10s.
I would give them at least 1.75 each after port and evrything else is taken out.Tune them a lil high also 35-36 and youll have more trunk and they will still sound great.
Come out to about 20 inches and youll have enough airspace for what you need for 2 10s I believe.

Works out to be 1.8 after you take out the sub displacement.
Thats too small really for a 12L7.It will sound Ok for rock/country/pop......but wont go low for rap/hip hop/ and stuff like that and will lack in the bottom end where these speakers like to live.

Net Internal Volume: 4 cubic feet

Then you take out Sub displacement.

If you take the demin. X*X*X/1728=cuft then you take out all the stuff in it like port displacement/ wood thickness/sub displacement/bracing.

You wanna tune high anyways with L7s.
36hz is a sweet spot shoot for that and youll be fine.

The size of the box has to do with output and power handling.
