That's what would be deterring me from using them. (I'm in 4 ohm land.) Even more so in a BTL configuration, unless supplies had to be unusually low for some reason.

Hybrids like STKs can provide more output power than conventional chipamps (which are ICs). Their reliability record wasn't all that great though (with Technics' modules enjoying a noticeably better reputation), so after using a lot of them in the late '70s to mid-'80s, manufacturers gradually went back to more robust discrete designs. You may still find hybrids in low-end A/V receivers, though even there they're not as popular any more.

hi, im using an stk 4050 amp, i built this circuit: STK4050 STK4050V 200W Power Amp IC - Buy Online @ AmpsLab Seems the gain is a bit low....how would i increase it?

look at datasheet an find application notes, these are some explanation to fix that.
