Stereo Woes

[Mayan-Viking]

Some time ago I upgraded to an Avin head unit and BAVSound speakers at the same time. Since then I have been getting lower frequency distortion in the right door panel driver. I'm pretty sure this distortion was not happening before swapping everything out.

I got in touch with BAVSound and was able to get new speakers shipped to me. I replaced the speaker and I am still getting the same distortion.

I then replaced the OEM HK amp with a replacement amp from eBay and again I am getting the same distortion.

At this point I am thinking it HAS to be the head unit that is faulty and causing the distortion (which sucks because I'm not looking forward to dealing with Avin's customer support in this matter). Is there anything else I am missing in this analysis of where the fault could lie?

No, unfortunately.

The last test you can run easily is your stock head unit with the BavSound speakers and HK amp, which will likely answer your question for good AND sound better than the Avin, while you shop for a better head unit.

At the risk of repeating myself, I'd suggest Dynavin if something like an OEM look is important.

If not, get a Sony or an Alpine, whichever fits these cars (I think it's the Sony).

I have heard a lot on the forum that the Avin's do not sound good, but honestly that hasn't been my experience. I got one for my e53 4.8is back in 2019, and did not notice a change in sound vs stock. OP, I got a an Avon for the e46 (with the upgraded DSP chipset) as well and funny enough with the bavsound speakers too. Haven't installed it yet though. I have no illusions that these are Chinese units that at best could be the luck of the draw of what you get unfortunately. Hoping its not the unit on your end.
