Hi guys. just wanted to know that for a small to medium size gig [ nothing professional ], can i connect my electro acoustic to a small amp combo of about 12 w and place the mics available at the venue which are connected to some really big speakers? will it sound all right? also, can i connect some really big speakers[ the ones for general use, not particularly guitar speakers] to my small amp of 12 w ? is there a way by which i can connect electro acoustic directly to speakers?
