I have an Onkyo TX-8511 receiver. Right now, I have very faint sound coming out of the speakers (similar to when you play a record on a turntable when it's not hooked up or amplified). When I turn the volume up, it increases, but is still very faint, even when it should be earsplitting. I have checked all of the connections, rewired the speakers, etc. As far as I know, nothing has changed from when it was working perfectly yesterday. Any ideas?

After a few years it may be time to consider a new cartridge for the turntable. The current one may have given up the ghost. You might also want to check that the output cables from the turntable to the receiver are firmly plugged in. They may have come loose if someone was moving things or cleaning. Yet another thing to consider is the input on the receiver may not be working. You can test this by plugging in a cable with RCA plugs on both ends and touching the pins on the unconnected end. If the input's okay you'll hear a hum.
Probably it's time for a new cartridge. They don't last forever, especially if you, like me, are someone who still plays a lot of old vinyl!

Just check your speaker cabling again. Make sure that all of them are seated properly, none is touching each other or the body of receiver. Rewire if necessary..
Are you using banana plugs for connecting speaker or just directly. Some times even a little tiny wire touching the receiver could trigger the protect mode. Be careful, since protect mode is sometimes not fast enough and it could blown a few trasistors in the power circuit.
Otherwise, do your bose speakers play out load on other systems?
Try some troubleshooting to check whether its the turntable or the the receiver.
What happens if you exchange the output cables of the turntable from left to right. Does the problem shift?
Does the sound changes from left to right speaker?
Similarly try on the inputs of the Receiver.. does the problem shift...?
This way you will be able to isolate the problem, whether with the receiver or the turntable....
Greg- Powered subs are better than non-powered subs (also known as passive subs), anyway I see the TX-8511 has no sub pre-out on the back panel, so you need to decide what sub you will use and run from the receivers left and right speakers output into a subwoofers speaker in from speakers then back out to speakers, look at the back of a subwoofer and you will see like 4 sets of speaker hookups 2 in and 2 out, what this does is takes the low end or bass and drops the signal to the subwoofer then takes the mids and highs out to your left and right speakers, unless your regular left and right stereo speakers have large woofers a sub is the way to go.
If you have a VCR it is easy. Just plug RCA cables into audio out right and audio out left (on VCR) and other ends into VCR audio in right and left at rear of your receiver. If there are two sets of video audio inputs, push button on front of receiver to agree with where you plugged cables in. (ie. Video 1 and video 2)
