Well, all I can say about my experience with the HK, it seems like I got all the frequencies back. Obviously some were being used to cancel noise, but seems much cleaner.
I would assume would work the same with the Alpine.
Downside is, yes you hear more road noise, tire noise, and exhaust. To some, they don’t want none of that. Me, it’s a truck. I put an aftermarket exhaust for a reason. Yes I hear my tires, but their 12 1/2” wide AT. I don’t expect a silent truck.
