This dreaded 03-00 came up on my D12s about two weeks into enjoying how great the sub blended into my system. My D12 came with versions 1.23 and I call perlisten, Erik answered and has been making every effort to fix my sub. He had my forward to version 1.27. Did not work. He sent me a label and Fed Ex shipped to San Mateo where a local dealer is that has a tech who can fix it.
Erik told me that Perlisten manufacturing in China received a batch of Mosfets that did not meet spec and my D12 may be the issue. I'm glad I bought a new one with a warranty, even if it is a perlisten
