Sorry you are having problems with that amp. How old is your replacement BASH amp? If you purchased the replacement amp out of warranty, it will carry its own a 3 year warranty. If it was replaced at N/C under the original warranty, then it would be tied to the original warranty period.
I know this is an old thread but I had exactly the same problem as DTS.
Have corresponded with someone from SVS who also suggested the Sledge to replace the Bash.
Contacted "Final Link Audio" dealers (I live in Brisbane, Australia) but so far got nowhere.
I purchased my Bash direct from SVS, is it possible to get the Sledge replacement?
Thanks if anyone is listening . . .
