Hi guys I am a member of a fraternity in Ohio. We have a good sized fraternity house with a really bad sound system. The party area is made of three separate rooms in the shape of an "L". When I first got there they had a small Sony 5.1 receiver and a really old Sony CD changer. There were 4 or 5 50 watt max power RCA speakers. The wires were run all over the place and were differing in lengths from 6 feet to around 50 feet. Even worse they just jammed the wires into the front left and right terminals. IT WAS BAD. With a budget of pretty much nothing I added a 110 watt per channel Pioneer 6.1 receiver that one of the guys had, two 150 watt 10in subwoofers that I had, upgraded the speakers to 8 JBL 5in venue monitors, added a Monster Cable speaker selector, bought 16 gauge speaker wire to make the lengths equal and used a digital optical cable. Anyways I am in the process of raising money and was wondering what I should get to upgrade the components. I want the use of the subwoofers and digital audio, but I am not sure what is best for my multi room set up. With a budget of 500 to 800 dollars what should I do?
