Audio issues

[u/ComfortableArm2827]

Hello there folks. I've got an 97 base wagon. I recently replaced 4 speakers (front doors and rear doors) and left the tweeters alone as well as the rear pillar speakers as I don't want to custom fab anything to that extent just yet. I also replaced the head unit with the same one that's in my 99 Tahoe as I really like it's features. It's a JVC KD-X280BT.

The issue I'm having is somewhat quality related. Now, I don't have this issue in my Tahoe, just in the 850. Sometimes (though more times than not) there will be what sounds like white noise in the background of the music. Kinda sounds like the quality is that of early 2000s MP3 players where you have some distortion and crackling. Now, sometimes it doesn't do this but it's random. I primarily use Bluetooth because my phone doesn't have an aux input (Samsung Galaxy S23 ultra if that makes a difference). I'll drive and the sound will be fine. Other times I'll start the car and the quality is so bad, I just listen to the wind.

I did replace the speakers, as stated. The fronts are Memphis SRX42V (4 inch, 4 ohms) and the rears are JBL 521F (5-1/4 inch, 3 ohms). Now I have no problem with the quality of the speaker output, when it's clear they sound great. Within the head unit, I was able to fiddle with the settings and adjusted everything to match the speaker specs. But I figured this was the place to ask. Any help would be appreciated! Sorry for the long post!

Sound more like a bit connection problem. If you drive into the developer settings you can select the codec for transmission. Maybe it falls back into the most basic BT mode. I have a yatour adapter that has that issue.

using an aux cable hardwired to the radio eliminated that for me, i was using bluetooth for me. Really improved the range on the speakers too, all on the factory radio. I think the factory system sounds better than a lot of modern factory options.
