This is weird though... for a non-nav car with the Hi-fi amp, the Android unit should play nicely. My Avin 2 worked perfectly fine in my old nav equipped Hi-fi sound system. Didn't run a single speaker wire or remove the factory amplifier. Sounded great.

It sounds like you are going to have to pull everything to see where the installer messed up. If everything is plugged in at the dash using the correct harness... you should have no issues AFAIK.

EDIT: How was the audio quality pre-Android unit? Any distortion present?

Not that I'm aware of... but to be honest I didn't really push it or maybe wasn't paying close enough attention. I was listening to some FM and most AM sports radio.. Hard to tell if a tweeter is blown with that... It is possible that tweeters are blown.. but I'm going to redo the install myself or see if he'll go over it with me so I can diagnose. I do remember as soon as I picked it up it was extremely loud at 5-6 on the volume fader and started to distort really early. That didn't seem right at all to me.

I'm going to test a few different audio sources and keep track of the sound quality and get back to you guys.

Thank you everyone for all the help.

I added my cubby and amp pictures for confirmation. For the amp you need to zoom in, but it has the info that I posted on the original post.
Well actually all you have to do if you want to ditch the current system but have it so you can return it back the way it was would be to buy an amp and then attach wires via a pin into the factory amp plug.

At this point all you have to run is two sets of rca cables from the front to the back. This will give you line level into the aftermarket amp and pure clean sound.

The part that has me curious though has to do with power levels.

If you over drive an amp it does sound like crap but it will sound fine till you reach the "over driven" point. So is the eonon setup as loud as the old stereo turned ALL the way up?

If its distorting at low levels then its not the eonon being to powerful but instead something else. The eonon could be defective.

The issue with running an aftermarket amplifier is you will only have 4 channels of output vs the 10 you get with the factory amp since the factory setup drives individual component speakers. The crossover network is handled internally in the amp. You would have to add in aftermarket x-overs and that is problematic when you donít have any spec on the factory speaker drivers or enclosures.

you could run an aftermarket DSP off the line-level outputs of the EONON + 2 amps, but seems a bit wasteful with the factory DSP sitting right there (and already calibrated). So I understand your dilemma. Perhaps use a small but high-quality pre-amp before the factory DSP that runs off the line-level outs?

Except the installer used the factory output speaker wires from the aftermarket amp instead of the line level output which as you can see are hanging loose. Sounds like you are overdriving the factory amp with the Eonon unit. Get the adapter that allows you to goes from RCA female connector on the Eonon to pigtail connectors and use those pigtails to wire into the connector that you bought to connect to the factory harness.

That would be an interesting experiment. But shouldn't be necessary with his current system. Unless there is a dramatic difference in the output levels of these android head units. I haven't ever heard of anyone having to use the low level outputs of one of these units to feed signal to the speaker level inputs on the OE amplifier. I certainly didn't have to.

Crowz is right... could be the Eonon itself acting up. Though looking at those pictures really makes me question the skill (pride of work) of the installer.

I experience phenomenal sound from my early Eonon GA6166 in my factory Nav, non-DSP Hi Fi system.

Here are my volume settings which work out just fine for me:



I simply used the long Fakra harness cable from the head unit to the FM tuner cable under the spare tire, aft of the battery.

E53s with non-factory Nav make the same connection to the factory harness up front and do not have to drag and bury that long a$$ cable all the way to the rear.

My hypothesis for the OP is that something else is wrong, perhaps in the head unit, especially if the tech connected the HU to the factory harness properly.

Thanks for the settings I will try the this morning.

Is the factory amp able to retain the EQ settings offline? If so I'm wondering if my volume or modications when I first got the car were never cleared and it's double EQ/Volume boosting? I read somewhere on the E46 forums about someone that reinstalled the MDI and turned turned down the volume and then reinstalled their Eonon or Seicane... But I wish I had read about the DACs on the Dynavin.. That would have totally changed my decision although I don't like that it's a locked system.
