Hard to quantify the difference, but it's massive that's for sure sort of like no sub vs turning on the sub. Huge change when you turn the sub on, really miss it when you turn it off.

But once I did the sub upgrade I caught the mod bug bigtime, now the entire Bose system is gone and I have moved on to performance mods.
