I have a problem. I was using a Philips 300W in-the-box home theater and recently purchased a Onkyo TX-SR500 reciever for my speakers. I have everything connected, works great however volume is low. I have each channel at +12, including the sub and the volume is still low. I need to set the reciever volume to like 50 to get loud enough sound. It's not much of a problem however Im afraid Im going to blow my speakers or something.
