Here is my JL Audio XD400/4, 4 channel 400Watt amplifier, 4 x 75watts (4ohm) which was removed from my Mercedes SL. It has had very little use, probably about 10 hours before it was removed. It works perfectly. The badge is missing due to the previous ICE installer losing it when it was removed from my car. I will see if I have a spare as I had some JL Audio speakers removed at the same time and those come with similar badges.
