I'll see if I can download either of those tracks to confirm but I doubt you'll need to tune lower than 40hz to play either.That all makes sense to me, except the 4 8s. I'm not looking for SPL, I'm looking for SQ while still having some knock. All the 8s I've listened to lately just do not get low enough. "Gangsta Rap Made me Do It" by Ice Cube is a great demo track for it. "It's All On Me" by Dr. Dre is another one. I've listened to every 8 I can find in the last week or so and none of them can drop the bottom out like I want. They get loud, but they don't get low. Maybe I'm just not listening to the right setups but I've been as thorough as possible.
The install time is a fair portion of the price I'm going to pay, including full dynamat, etc. These guys did my system back in 2014 and they did a very good job back then, which is why I'm returning.
That said, as we explained earlier you're fighting a losing battle against Hoffman's Iron Law and any way you slice it you're either using small piston area or larger piston area with less stroke. You just hit the wall with how much air you can move in that style vehicle and generally speaking the acoustics of trying to get good low frequency while keeping functionality of rear seats isn't great in that body style.
IF you can get a ported box down there somehow that would help some but I don't think believe one or the other out of the ideas presented is going to be a dramatic difference.
I would definitely agree that judging components based on the rather perfect-world conditions of a listening room in a shop is not going to give you an accurate expectation of what to expect when mounted in a vehicle.
