hey man, I know the feeling. I rented a condo and had a nice sound system. Got a complaint everytime and all I did was watch movies at moderate levels. It got to the point where I said fine...I'll be nice and not use it. Then I got another complaint when all I was doing was using my TV speakers! I was like WTF, people are being ridiculous here. Anyways, eventually the condo association took my side.
You can't expect to move into a shared community and have everything be all peace and quite all the time. I would tell you to just put up a show and game like everyone else and say yeah don't worry im fixing it. Then just keeping doing what your doing. Condo associations are gay and ridiculous with their rules.
First chance I had I got out of my condo association. Never ever will I do that again. It's a bunch of BS will all their rules and anal retentive people.
