The Random E46/ZHP Question Thread

Differences in compression make a huge difference in any listening environment.

Does anyone know of a thread, or have input, about adding an aftermarket deck to the HK system? It's time I start figuring this out. I installed 12V for years and this factory system is just meh.

If you say so. I'd bet double blind, the vast majority would have a difficult time discerning the differences between direct digital, aux, and bluetooth when factoring in engine noise, tire noise, and ambient noise.

This. I stopped noticing a difference once I reached 320kbps, at least with the stock speakers.

Random question..... when I go to unlock my car manually, sometimes the beep sound happens and the locks don't unlock, sometimes while sitting in the car I unlock it using the button right next to the hazards and it doesn't unlock. It's weird.... has this happened to anyone else?

What do you mean "unlock manually," that you put your car key physically in the car door and turn it?

I have never experienced either of those situations, but one distant possibility is your car's battery is going. How old is your current battery?

This is a shot in the dark, but maybe it's your GM5 module?

I have experienced similar things - several doors will remain locked even when I manually turn the key in the lock or use the button on the center console. I found the site above after researching the issue but I have been prioritizing other maintenance.

I think this is the problem, I'm 99% sure this is it. All the symptoms point to the gm5 module. I didn't see this on that site but my dynavin unit doesnt turn on when I start the car sometimes. Maybe that has something to do with it too.

I honestly thought my alternator or battery were giving out but now that I read info on that link, I'm sure it's the gm5.

Did you have that same issue and did you fix it in anyway?

Thanks for sharing that website man, it will be repaired as soon as I can take the module out and take it to that guy in Torrance, that's like 1 hr away from where I live

Respectfully, this isn't me saying so; it's a fact. One of my gripes with younger generations is the decline in appreciation for great sound. Yes, I'd venture it would, indeed, be a majority having difficulty noticing a difference. Me (and plenty of others like me), on the other hand, can absolutely tell the difference in a blind test of compressed vs mostly-uncompressed (CD quality) audio. I'd bet pinks on it.

Now, could I tell the difference between the same file being streamed over a good Bluetooth, auxiliary, or a CD? Only maybe, and probably not.

As far as cabin noise being a factor, yes, that CAN make it harder to appreciate the difference. With that said, though, we're talking about newish BMW's here, not old Hondas. The interior of our cars are actually very quiet. So play a WAV file vs a 128kbps (and sometimes up to 320) inside my ZHP and I'll notice it immediately. I can promise you that. This has a lot to do with my experience with good sound. For so many, you don't know what you're missing. But once you've tasted it done right, car audio included, it's hard to go back

Back in my downloading days, I wouldn't touch a file under 256kbps. The quality difference is very obvious.

And I can tell a significant difference when streaming any audio over Bluetooth.

I think the "problem" with "young people" these days is that everything you buy already comes with speakers. A few decades ago, you wanted speakers on something? You had to buy speakers for it! And there was actually a store in town that offered speakers!

Also, the vast majority of pop music made in the last 20 years is crap

You take that back, Carly Rae Jepson is a Canadian national treasure!
