Hi, I'm from Germany and I have bought an US Amps Merlin MD-23 Amp on Ebay earlier this year. I never opened it because I didn't have time to work on my car. Today I finally wanted to look inside my new Amp and I was shocked. On the Packaging Box and the Chassis it says MD-23 but on the Board it says MD-22. So I guess I was deceived by the Ebay seller. But I wanted to be sure, so is there any attribute that could tell for sure which Amp I do have here? I'm looking forward to any reply you can give me =) Greets Eric
