So I've been I've been a huge fan old the older Eclipse titanium SW9122DVC/aluminum sw8122dvc subs that TC Sounds made for them here in the states and before Eclipse cheaped out and became trash. Anyways I finally got my hands on a nice 12" Eclipse titanium SW9122DVC that I want to put in my SUV (Mitsubishi Montero Sport) but when it comes to custom box building/tuning ports I'm lost. I can definitely put one together & considered buying a box design from CAF since they're 50% off and only $7.50 but I'd also like the sub to fire up and port out the back. I added some examples but maybe someone can help point me in the right direction for the correct box size and tuning of the port? I dont want to buy a pretty fab but heard the Skar vented box isn't to bad?
