I am currently set up with a single run of 1/0 welding cable (OFC) with only the positive line on a stock battery in my 05 Impala. Stock alt too. Sundown SAZ-3500D, 2x Fi BL 12 D2 wired to 2ohm in a shitty enclosure. I plan on (in the very near future) grabbing me a few batteries to replace the stock under the hood and have 1-3 extras in the back and also running another line of 1/0 for the ground. As my Fi subs are slowly giving out (my fault), I plan on reconing them and giving those to my brother and picking up a couple Digital Designs 9512s with whatever upgrades I can grab. I read a few detailed threads across the internet, watched some videos from people that seem to know the facts behind what they are talking about, and played around with WinISD and Bassbox Pro a bunch to get a better understand of what an enclosure SHOULD be like.
As it stands, I can fit an enclosure of 17"H x 34"W x up to 40"D in my trunk facing forward with the read seat removed. I have never competed in a competition, and actually have only spectated one recently, but I hope to compete in the future. So with that, I would like to create an enclosure that would have a removable port to tune separately for daily and for SPL.
What I hope to get out of this thread is the basics of what a GOOD enclosure needs.
So far, I understand that angling won't always yield the best results and should only be applied to the pressure points of the enclosure. I also understand that subs in an enclosure have a sweet spot of how much volume they have to work with.
I will be picking up a TL for myself to find small gains once I possibly can, but for now I wish to just learn more.
Any tips are greatly appreciated.
