So I've only been playing a short while and need some help with my head/cab setup... I was given a Peavey cab (15 in speaker/1000 watt) and replaced the old speaker with a brand new Peavey black widow 1502. Both the cab and speaker are 1000 watt/4 ohm. I tried to power it with a TC Electronics BH250 head (250 watt) but it sounds awful.... I figured since I live in a condo I don't need it to be super powerful (right now), so the 250 watt head would have worked. Apparently I was wrong... My question is, what is the least amount of watts my head should be to power what I have and still sound good??? I was trying to get away without spending too much money but now, just need to know the least watts I need so I can make a better decision. Any and all help would be greatly appreciated. Thx!!!!
