Suggestion

As with most stereos, try running the treble up to 7/8, the base to 4/5/6, and the fade to 3/4/5 to the rear (it is up to you).

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

I just bought a 2003 C4S. The Bose radio package doesn't sound that great. I've read the manual. Any tricks for getting great sound out of it? Thanks, David

POST 2Original post

problem is it has the "MOST" set up you really can't add anything to it i will say one thing it (BOSE)is a whole lot better than the basic set up roy

POST 3Original post

That's scary. I have the Hi-Fi in my Boxster S with the additional 4 rear speakers, and it sounds really bad. People have good opinions on the Bose system. I haven't seen one yet working at high volume. How do you rate it from 1-10? Can you please rate any other factory car installed stereo? Thanks

POST 4Original post

factory stereos run at 2 ohms, any aftermarket runs at 4 ohms...quality depends on what you're used to.

POST 5Original post

I haven't read the manual (never do), tell me if I need to know anything good. My 2003 Targa has the BOSE system, I have had good luck with it so far. As with most stereos, try running the treble up to 7/8, the base to 4/5/6, and the fade to 3/4/5 to the rear (it is up to you). These seem to help a car system sound better (for the driver), do we really care about anyone else? Welcome to the forum, is this your 1st P-Car?

POST 6 / ORIGINAL POSTEROriginal post

The manual doesn't tell us much. Same here, heavy bass, treble at -3 more rear on fader. It just doesn't have the heart that my 95 993 C4 had or my 02 Viper coupe. Almost tinny

POST 7Original post

As far as factory stereos go from any make of car the Bose system is decent but a far cry from what you can get for a little more cash after market.

POST 8Original post

just replaced the entire system with 8ch ads amp, touchscreen voice recog. pioneer head unit + nav, ipod. tuner is stronger, cds sound much better (and I can play dvds and mp3s). wasn't cheap but wuttuyagonnado.....

POST 9Original post

The question was for the MOST system that started in 2003. What year is your car? Jeff

POST 10Original post

Supposedly, this is the best sound system Porsche has ever had. Probably true, but it still leaves much to be desired. Subs are too muddy and overpowering, a bad combo. I turn the loudness OFF, and even have the bass settings in the negative. Treble I up up a bit. Still not great, but not bad. Best sound system upgrade has been PSE. I rarely have the radio on anymore.

POST 11Original post

'04 c4sc. The speakers sound a lot better with my new amp and the equalization abilities of the pioneer. If I were doing 12k+ miles a year, I'd upgrade the speakers too. I mainly did this for the nav (pioneer head unit w/ motorized screen can't hook up with a MOST amp), the sound was a side benefit. BTW, I have the cd changer for sale if anyone cares.

POST 12Original post

but the HK Logic 7 system in my E500 SHAMES the Porsche system. It's not even funny. For CD's here's what I use in general: Loudness OFF. Bass at -3 or -4 Treble at 0. Fader and balance centered. If you can't find settings that "work" for you, feel bad for 2 seconds, drop the windows, and enjoy the F-6!

POST 14Original post

Wheat, How much for the CD Changer? PM me. I will say this about the Bose system, it greatly depends upon the source material. Most people wrongly assume all CD's are created equal, they aren't. I have some selections that sound fabulous in the 996 with the BOSE, others that sound like garbage and I have found this to be true of any other car stereo system I've ever tested. Basically, you have to find settings you like for "general purpose" playing and choose the source material that sounds best in that particular environment.

This is a source reference. Confirm exact model applicability in the original material.
