I was given a 10" sub and need help to hook it up. I have a Onkyo 503 7.1 receiver, old JBL 8" three way speakers and a JBL center speaker. I have a open floor design and the living, dining, and kitchen are all one big room. Seperated by furniture, the lenght is about 30ft and the width is about 14ft. We have ceramic tile in all the areas. I want some solid bass but like alot of highs also. Any help would be appreciated.
