I run a svt3 pro, I purchased a new svt 810e from zzounds, very disappointed that thing was farting out at mid volume without any eq. My question is, I have an old peavey 15 bass cab, 300 watt b/w. Can I put one of their newer cabs rated at 500 watts with it or would they fight for power. Cant seem to find another 15 cab like my old one, even empty. Love the growl of the plain old black widow in a ported cab
