Has anybody ever installed a deck into a mercedes, I have 2 to do and was looking for a heads up. The first is a 92 E190, second is a 99 C320. The first is the most critical as its slated to start tomorrow. I''m just worried about the alarm system or anything like that.

 

ok so buddy didnt show up today so I have a couple more days. My question is how do I maintain the factory amplifier that I assume it has because of posts that i've read searching. Also does the alarm or anything else tie in with the radio. Any help from people who have been here would be great.
