[TAKECLEAR_86]

Just to preface, I'm almost clueless when it comes to car audio, but give me a couple pairs of audiophile level headphones and I can tell clear differences.

That being said, I just installed this unit into my 17' 86 a couple days ago. Everything works as far as I can tell, but I noticed some issues with my speakers. When I play music that may have some bass to the track, at higher volumes, enough to help drown out road noise, the audio has a barely noticeable static/distortion from the speaker on the dash. Not that bad, but I notice it and it is very annoying. When I set the EQ and everything to flat, audio is perfect, no static/distortion at all.

It's a brand new HU so there's no information online other than from Pioneer themselves. I'm not looking to add a sub/amp anytime soon as I may end up going the OEM+ route early next year.

My main question is, does adding a new HU in our cars mess how the factory amp/door speakers function? Would upgrading just the speakers potentially help?

I did a search on the forums, so I apologize if the answer is already out there, but every thread I found mentioned aftermarket amps/speakers/subs as part of the installs. Any post with just a HU upgrade said their audio was improved across the board.
