EONON Amp vs BMW HI-Fi Amp (bypass?) - Page 5

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.

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 don’t 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?

Yeah I do Boost the treb a bit and bass slightly. Kind of always do a rock mid scoop because I listen to metal. Gonna try that tonight

I hear that. I love a nice (and fast) tight kick drum too. It's one of the reasons I've always preferred sealed enclosures to ported. Bandpass can hit quick too, but a tight sealed enclosure always tickles my fancy.

Good luck, fingers crossed for you.

What eq settings? His car is a non nav, non dsp. All it has is bass and treble right?

Yes true. Not an equalizer like DSP vehicles... but common terminology for most.

ok, sorry for the delay everyone.. It's been a busy week and today was the only time I was able to take everything apart and have a look.

So I plugged back in the old system to check the settings and to my dismay they were already reset to default. Didn't look like it retained any of the settings, but I did turn down the volume all the way. Went back to plug everything back in and the sound was pretty much the same. I tested the radio and crash cymbals seem fairly clear on radio, but when I run it through the bluetooth I get a nasty crackle whenever a crash hits.
For reference the songs I am using are
Caligula's Horse - Dream the Dead and Bloom
Silent Planet - random songs
Tried another song that had good mastering because these are fairly good bands and Opeth still had some high hat crackle. Their albums mastering is really good and shouldn't present any problems.

It's leading me to believe that it's the bluetooth connection on the Eonon that is poor quality. I'm going to email them and see what they are willing to do. Sound quality is important to me and I'm assuming this will impact the sound even if I bypass with new speakers and an amp.

Any other suggestions are appreciated.
