Hi guys, yesterday my amp blew on my YST SW800 sub. After reading a few threads Im at a crossroads of wether to buy a new sub or get a new plate amp form BK? I was thinking of replacing the original Yamaha amp with the BSBP 200. Size wise it will fit with a litte bit of a modification, power wise I think it will be OK too(not sure to get 4 or 8 Ohm as the yamaha maunal for my sub quotes the driver as 6 Ohm!!!) unless you guys can see any problems I have missed? I was very happy with my sub (when it worked) and dont really want to trash it. Any adivse welcome. PS- this is my first post and great forum.
