    Lightbulb Attenuation

    I'm just wondering why this isn't considered a factor? I see people recommending daisy chaining cables and splitters of all types and to just buy adapters because they're cheaper than a new cable. Don't these simple solutions just make your finely tuned $2000 system a moot point? I just came here trying to piece together the wiring for my set up and after a few hours of searching I found that everyone seems to have half-buttocked their solutions.

    Attenuation is a HUGE issue in car audio. You can't ignore it. Buying a 20 cent splitter, or even a 3 dollar splitter with gold ends (copper and silver ftw...) just creates a weak link in a shielded cable. I mean look at the packs of cables strapped together, you expect someone to buy a RCA to 3.5mm cable from radio shack, pack it up nice and tight against 15 other wires, and not get distortion?

    I saw a single scenario where someone decided to use a PCI card with RCA jacks on it... No one has yet addressed the issue of balanced sound VS. unbalanced sound. No one's said anything about the difference in line level output between the computer and the amp. Just because you hook it all up and noise comes out without blowing the speakers at varied volumes doesn't mean it's working...

    I come across as peeved because of all the flaming I see in forums, and I know that when I started asking questions I'd get all of these "obvious" solutions and be told to learn how to use the search function. I want help in designing a good sound system, not a flashy sound system, and I need help from people who are aware of these issues and make an attempt to work with them rather than simply pretending that the issues don't exist.

    While the issues you bring up are important, many of the people who are installing CarPC's are more interested in the PC functionality of the system and not so much the sound quality. Many keep at least some portion of the factory sound system, if not the whole thing. They simply aren't really concerned with changing the sound system, factory is good enough for them.

    That being said, there is a pretty large group of us who are in search of something more than factory. You must not have searched very hard, because in the "High End Solutions" sub-forum of the Car Audio forum, there is a group of people in search of sound quality and advanced CarPC tuning solutions.

    We even have a moderator who is a champion sound quality competitor (RedGTiVR6).

    I think you'll find what you're looking for by posting in the "High End Solutions" sub-forum.

    there are a few of us that are using balanced signals.

    And we regularly talk about matching your gains to your source signal

    what is your question? we can help you out

    edit: i'm not sure what your major gripe is though, i just read your other thread and i felt as though everyone was pretty calm and helpful to you.

    and what is wrong with a flashy system? :-)

    Otterski,

    You threw out a bunch of terms without providing any constructive criticism someone could build upon. Example?

    You complain about attenuation, yet what if I were to attenuate an 8-Volt signal to say something like 1.67-Volts. Your posting implies that would be a bad thing; however, what if the goal of my attenuation was to step from an Eclipse deck (using a balanced output) to a piece of pro-audio gear (like a dbx DriveRack) modified for car use?
