Had the same issue with my IFI so I took the plunge and took the electronics module out of the sub. I may have located the problem, not sure yet, waiting on the replacement part. There are several decent size capacitors most of which are 4700uf 35v and just 1 that is a 4700uf 25v. It was the single 25v cap that is leaking from the top which typically indicates it is blown. I am hoping that this is causing my channel to be dead at low volume plus the low sub output.
