Ok, my bass player is getting a bass Amp for now he is going for something less expensive like a $400 dollar bass amp, Its going to be a combo and its probably going to be something like 100watt to 150 watt my guess. SO when i play live will this bass amp only be good for a room of 100 people or less? I mean can you mic it? if so Would i need to have subwoofers in the Pa, or would my 2 500 watt 15 inch yamahs handle it, im pretty confused on how this will work for live use. Please help!
