I bought this cheap RCA 400 watt surround sound at Walmart for $150. It wasn't that great and I decided to return it anyway and go with an Onkyo system at Circuit City (still deciding). Anyway using the RCA tonight the volume wouldn't go past 43. It had been going up to 50 which is the max so why now would it just go to 43?? I unplugged it to reset to see if that helped and the same thing. I'm returning it anyway, but just found it odd the receiver was doing this.
