Anybody had any luck with aftermarket audio companies in the DFW area. Quotes I've got have varied from $1400 to $4700 and I really just want to replace the speakers (tweeters if possible), add a small sub and a box, amp, and that's pretty much it (obviously will get whatever is needed I'm just not very well versed in audio). I'm not an audiophile, and really don't want anything too crazy or high end. In the past, I've always just bought upgraded sound systems in the cars beforehand from the factory, but I hated the HK in my old CLA so I didn't spend the money. Just curious if anybody here has had anybody replace any of their audio components and if they've run into any issues afterwards. I'm more or less at a loss of what I need and who would be reputable without just padding commission off of someone that doesn't know much about audio.

Have you ordered or bought a Giulia yet?

The reason I ask is that most folks here presume the HK system is
superior to the default system in the Giulia. I have 50 years experience
in audio/HT (audiophile if you like). I have not heard the HK system.
However, IMO any "surround" system in a car is unnecessary overkill.
Surround audio is for large home rooms or dedicated home theaters
and for audio sources designed and coded for surround. In my home
I many times listen to my 2 channel sources in surround sound versus
plain stereo as it adds some natural sounding ambiance. However,
a car's interior is not appropriate for surround sound to be effective.
The ambient/background noise level in a car is much higher than that
of a usually very quiet home room. If you want your car to have the
way over emphasized boom-boom of a gang car then the car sound
dealer might be able to fix you up with an extra powerful amp and
some high power handling speakers, but most of them will way
oversell you on what you need.

The huge surprise for me that came from my dealer in-stock Giulia
without the $900 HK package was how good the default system was.
If you have the chance, listen to the stock sound system first with the
engine off. That way you can listen seriously to the sound in a quiet
environment. That's when you can evaluate the sound and lack of
distortion and hopefully smooth/flat frequency response. Try to find
a clear and clean high definition FM station, same with any Sirius/XM
channel or some of your own high definition tunes (not poor MP3 sources).
A high sound source is very important to test a car system. No sub needed
in my Giulia and I'm picky for clean low bass/amp is fine. A home is very
difficult to design a speaker for because the room environment has a huge
affect on the sound. A speaker that sounds great in your room might sound
significantly different in your next house/room. A car is relatively easy for
a company to choose a stock sound system because if it is done right it will
sound the same in each car.

I have never heard a stock car sound system that I thought was very good.
This Giulia stock sound is excellent. I tested it with very high quality sources,
with low bass (synthesized, pipe organ, stand up bass and cello), difficult
mid-range sources like female voices and also highs such as solo and massed
strings. I used rock, jazz, pop, rap and other types of music. The sound is
flat, low distortion, dynamic and has very tight/good low bass and non-irritating
highs. Give it a listen and it might save you plenty of dough.

I'm sure some here will dismiss my advice and nice short post! :D

I'm definitely not a golden eared audiophile, I listen at lower to moderate volumes and I have the non HK system but I agree with JuliaQ4-Nut that it sounds great. I enjoy listening to a variety of music and talking books in the Giulia and have given up the idea that the speakers are something I'm going to have to upgrade. I'm certain their are better systems available but the stock system is working well for me particularly after being used for a while.

The best post(that I am interested in) i have read after owning a Giulia.
I have a stock audio system, the clarity is too good (if you discard the cracking noise when connected via usb)
Though I am looking for more bass. I have a spare 125 watts compact subwoofer(infinity) , any idea if it would be enough, if i place it in trunk?
The back seats are pretty thick, will I be able to hear a thing? (if i have it installed that is)

Prasanth, thanks. Sorry but I have not even checked out the speakers or amp wiring yet in the Giulia.
Too busy having fun driving it! I would be careful pumping up the bass in the current system. Just a
slight increase in the bass setting of 3dB's (slightly noticeable increase in sound) requires twice the
output from the amp. If you crank up the bass setting much above zero it can quickly drive the amp into
distortion, bad for the speakers. In my Giulia I have both the bass and treble set to zero. I have the
fade set in the middle. Some prefer the fade slightly to the rear for a little ambient sound. I love the
sound clean and accurate sound I have now!

As far as your sub, car Infinity is probably very good gear as it is in home audio. You say 125 watts, is that
self powered sub, sub spec or do you have an amp for it? The watts number is quite insignificant unless
we know the sensitivity (efficiency) of the subwoofer). How loud a speaker will play is dependent on the
sensitivity of the speaker and how the wattage of the amp is specified. I'm not sure if that sub/amp
would make a significant improvement depending on how low it goes below the 4 default woofers in the
Giulia which sound great to me, as in excellent transient response (tight) and low distortion. You might
have an expensive charge to install it ln the trunk and possibly need a component to split and direct only
the lowest bass to the sub (what size is it ?). I guess it will not make much if any improvement or
extend the bass much lower or louder from the trunk. Good luck to you and Reeplay87! :D

PS: I was on the freeway awhile ago at 65mph. I scanned a few Sirius/XM channels for good quality sound. Many songs are poorly recorded with little quality bass. Many folks turn up the bass control to compensate, not a good idea. I listened to some Bob Marley (Exodus?) and Babyface (Exceptional?) plus some clean Rap channels. I heard some excellent bass, plenty defined and loud.
