I am not stuck on sundown subs lol, I am open to all suggestions. Just like how they look and perform as well so that's a plus. Nothing is set in stone as depending on if I am able to get another saz 3000d. Which could open up other options of subs as well. I don't mind blocking my back window lol, and as much as I would like to go seats down to open up more room I can't. I just know that the sundowns tend to perform rather well in smaller enclosures so I guess that kind of played into my path to them lol.
