OP, I work for the court in CS.
Nothing I say here can be taken as legal advice; i'm not a lawyer (yet!).
Here's what is going to happen:
Take it to a pretrial conference. There, talk to the City Attorney and she will give you a 25% off discount. The Court definitely looks down on "party crimes" (noise complaints, alcohol related offenses etc) and there is very little leeway.
Do not take it to court, just talk to the CA like I said above, and get deferred adjudication. Basically keep your nose clean for 6 months and your ticket goes bye bye so long as you paid it.
Speaking of, it sounds like you're gonna be paying about $350 for the ticket. Court costs are so high because the Legislature sets how much you would have to pay. It's pretty ridiculous and no one knows about it.
When you go in front of the CA, do not mention the whole "cop kept trying to tell me my ID was fake" story. There is no way to prove that and even if you did, it would not mitigate your loud music.
If I were you, I'd pay half the ticket, and then lock my **** up. Especially the gate. If the cops show up go inside, turn the music down. Don't answer if they knock on your door.
Hope this helps man. If you have any questions my email is in my profile.
