Alarm Faint / Loud Erratic Sound

I am experiencing an issue with my 2006 Sprots Sedan. I walked out to my garage to get ready to leave for work and I hear this faint to loud sound coming from my alarm it sounds like. Keep in mind the car does not ever get driven and spends a lot of time in the garage as it is a garage queen. I start it every once in a while and run it for a period of time. It is an erratic faint or loud sound coming from the alarm and I have no idea why it is doing that. I started it this morning and started with no issues. I have the alarm disabled so the sound is not happening. Any ideas why it is doing this? I have searched the forum with no luck on finding out why it is doing it. Any ideas or information would be helpful. Thank you in advance.

Sounds like the alarm speaker is going. Mine used to sound like cats being drowned until it was fixed.

Well the alarm is not going off, but it does sound like that cats are fighting from the noise it is making. It ends up being loud then a quiet sound. Where are the batteries located? How do I replace them? Is this a DIY replacemente item? Thank you.

My car was in the dealership, and I was feeling lazy, so I had them replace the speaker at the same time. I think that someone here posted a pic of where it is; do a search and see if you can get anything.
