2015 Sedan 5.0 After market audio upgrade

[Tony122]

Not impressed with the 14 speaker system. Looking to upgrade/replace the entire system but keeping the factory head unit. Looking for advice from people who have done this already. I am starting with deactivating the factory Sub and replacing it. Also would anyone be interested in me posting progress?

The head unit tunes the frequency response of each speaker according to characteristics and location of each OEM speaker, and to account for the impedance and efficiency of each OEM speaker. Therefore, it I am not sure how you are going to overcome that issue. Changing out the sub has been done, and should not be a big problem.

To upgrade the entire system and overcome factory processing you will need an aftermarket digital sound processor and a proper tune.

A build thread would be awesome, especially if you have lots of pictures.

Someone tried that about 6 years ago (wild guess) and documented it as he went along on this forum. He was a professional installer and it was for a car stereo competition. He got almost all the equipment for free or highly discounted from the vendors because it was for a competition and a lot of people would see it. I would estimate that the install would have cost at least $20K retail otherwise.

He started out with the idea of using the signal processing to make the frequency response flat coming out of the OEM head unit (un-doing the adjustments the OEM head unit makes that I mentioned in my first post), but after much work (and a lot of arguing with me on the forum) he finally gave up and installed a new CD player under the seat, bypassing the OEM head unit, and going straight into his own pre-amp and then amp(s) and speakers.

People don't realize how much signal processing there already is in the Lexicon system, and it is hard to undo it and make it sound right. Plus, it won't work well at all in synthesized surround mode.

$20K?!? That's almost ridiculous. I would love to see that thread, do you have the link?

Bypassing the factory head unit would probably be the easiest solution but you would lose factory volume and ipod control. There are DSP's that have bluetooth, USB audio and aux inputs if you don't want a CD player.

Quite a few DSP's have been released in the last few years that allow easier factory integration. The JL Audio Fix line is a dedicated OEM integration unit that automatically calibrates, removing factory time delay and eq to output a relativley flat signal. A second DSP is required for more advanced tuning but with proper install the system would sound better and cost significantly less than $20k unless you want competition level equipment and installation.

This build thread helped me when I was upgrading my system.

The $20K was my estimation for parts and labor at list prices. As I said, he got the equipment for free or highly discounted prices and he did the labor himself. I priced the equipment he installed (all of it absolutely top of the line that filled the entire trunk) to come up with the equipment cost estimate, and the installer did a lot of highly customized fabrication with spectacular lighting, etc, in the trunk.

I don't have a link off-hand. You can use a search engine like google (include "site:genesisowners.com"). He had lots of pics.

I am looking into doing a DSP and replacing the factory amp and all the speakers. I just cant find what if any features I will lose by not using the amp.

 

[Saintt]

The factory amp sends vehicle, phone and navigations alerts to the front center speaker so unless you completely remove both then the only feature you'd lose is surround sound.

Isn't that the head unit, and not the amp?

 

[Saintt]

No, the head unit is just an input, the actual processing is done in the amp.

I'm not worried about losing surround sound for music. I am hoping I don't lose the directional warnings from anti-collision. I cant find any source material to say what specifically is produced from the amp or if any speakers are not powered by the amp. I have seen where some installs sounded bad due to not tuning the center channel with the aftermarket amp. So for now I may just bypass the amp for all the door speakers with a DSP and amp with 2 sets of component speakers. I will post what the plan is in this thread when I believe I have a solid grasp on it. Then start new threads with each piece of equipment so I don't make a massive thread that won't load. if anyone has ideas or requests please inbox me. I travel for a living and usually only have a few days to a week a month to get work done, so this might take some time.

If this is the case I should be able to grab the signal before processing in the amp and not need a DSP. But from what I have seen so far is processing from the head unit and just regular amp magic from the amp.

 

[Saintt]

You'd definitely have to bypass the factory amp for best sound. You will still receive vehicle alerts but the music volume won't decrease.

All speakers are powered by the amp, check the amp pinout.

The head unit sends signal to the amp via SPDIF, I'm not aware of a method to grab pre-amp signal.

I added an additional subwoofer to the stock system and think that's all that was needed, although you may differ. Adding the sub was easy and after my experimentation, you can install one in under an hour if you'd like. The stock system has pretty good midrange...and although I think the high range could use some help as well, I left that alone for now.

Wow! This guy's work is amazing.

Wonder what something like that would cost?

Can you check out that link? It is not working for me.

I installed the aftermarket amp and sub today. Since it has been posted before would anyone want a how to?

I'm guessing $10k and a week of not having a car. The equipment probably only cost $3-5k but the labor and fabrication is gonna cost.

It is used in a lot of home theater systems and computers. Its only a matter of time till someone makes one for car audio. Probably the day after I get a DSP working how I want it. LOL

 

[Saintt]

They already have just not for this car, the Mobridge DA1 would be the perfect solution.

Supposedly the Lexicon 17 spkr. has algorithms that fill in for the satellite compression. I've never much available that seamlessly upgrades factory sound w/ out a ton of mods. But I'm not that into it anyway....
