Recently had a local with an old style 2970 (150 ish watts) and he told me he was going to add a Texas Star 350 Hiiii Driiiiive and really kick some butt.
Oh yeah, that is going to work well......
Been there, done that (accidently of course), the TS 350 only took one key down when I realized my mistake..... had DEI's in it, New Toshiba's were in order .....
