My WT is a great amp but the problem is i cant get a lot of power or head room out of it running @ 4 ohms into my 4 ohm cab. I cant bridge it because of the ohms so my thoughts are more power. (Im worried about damaging my speakers) I run out of head room and my output limit lights start going crazy. So I see that the SVT-IV can do 2, 4, and 8 ohms and i can bridge @ 4 ohms too to get i believe 1200 watts. (i own a PR-410HLF cab and it is 600 watts rms @ 4 ohms and 1200 watt program power handling) So I'm thinking the SVT-IV will give me the head room i want and a great tone as well. What do you guys recommend from your past experiences and thoughts?
