1st off, yes I have done a search. Ok, we are going to be playing at parties and whatever so we need our singer to be heard. Here's our gear: 350w bass amp with 4x10 and 1x15 60w TSL Guitar amp w/4x12 Drums We had a look at the search, and quite frankly the answers varied so much that it didn't mean didly squat to us. We saw 2w per person, 5-10w per person, and 300w in general. Question is, would a 300w @ 8ohms/side (600w total) do us ok with a pair of 400w 1x15 pa speakers? This would only be used for vocals, unless you can tell me what else should have to go through it. Thanks guys/gals.
