PM-68 Marantz Receiver keeps shutting off sound after a few
Very frustrating! The receiver (regardless of source and output/types of speakers) continually kick out after a short period of play. It will play wonderfully then "click" off occasionally coming backing on, only to click off again.
I feel like I've tried every permutation of possibilities (from different wall sockets to speakers) to try to nail down this problem...
Purchased this second hand sight unseen from forum for relatively cheap. thinking i got ripped off at this point.

You need a cable that has a 2.5mm stereo connector on one end and two "RCA" connectors on the other end. Plug into the headphone connector on your device, and the other end to the back of your receiver's "aux" input.
The key to running the Bose 901s is to have the equalizer inserted into the tape monitor loop. Most 'old school' stereo receivers have tape monitor inputs. On an AV receiver, the VCR or CD analog inputs/outputs could be used but you will be limiting your listening to stereo sources. Please be aware that some AV receivers will not allow you to select different audio and video sources. The Marantz NR15xx, SRx004 receivers are pretty flexible, and allow you to pair up a component audio input with an HDMI (or other) video input. (No surround sound in this type of setup...)
First off you will need to do a little bit of trouble shooting. Is the source (dvd, Blu-ray, cable box, etc...) plugged into the receiver with the standard red and white RCA cord or by an optical (toslink-fiber optic) or digital RCA (orange color code). If you are connected with a standard RCA cord then that it your problem and you need buy digital cord that both the source device and the receiver can accept (toslink - http://www.we-supply.com/browse.cfm/optical:-audio/2,779.html or Digital RCA). If the connection is now correct then you need to make your receiver do a "test-tone" to insure that a signal can be sent to every speaker (this is an internal test that just checks the speaker connections). If the tone tone operates correctly then you know the amplifier is functioning. If both of the mentioned things are now done and still not surround output then you need to check the internal menus on your source device and make sure that it does not require you to manual change a setting in the audio menu to make it work (i.e. change from 2-ch 44KHz to 5.1 or 7.1 or Dolby Digital or AC3 or some other surround sound protocol.)

I'd say you DO need to evaluate how the PSW is attached. I can't find the specific manual for it but the prescribed way for most subs that accept speaker level inputs (and HAVE speaker level output terminals) is run one pair of speaker outputs from the receiver to the sub and daisy-chain the Klipsh speakers from the sub.
Check all speaker connections. unplug everything.. start with just L and R speakers. Do a mic calibration..also check all your source inputs to the amp. start from the basics. Is the amp still under factory warranty? I used to install marantz...also make sure unit is well ventilated. IF you are using audio zones in your place..with in wall volume controls..make sure they are impedance matched. VOLUME may be set to high...overdriving the outputs..eventhough audio may not be loud. Set volume to -30...?
I wrote this for a different receiver, but if you account for minor differences to your receiver this will work just fine.
There's good news and bad news. The bad news you need a separate amp because a multichannel receiver with Bose 901's attached as recommended for a standard stereo receiver will only sound right in STEREO on stereo analog material. The other speakers around the room are not designed to receive its Active Equalization and if you engage your Tape Monitor you will NOT BE ABLE TO HEAR DIGITAL sources at all. Tape Monitor is for analog stereo material only and on modern AV receivers it disables any digital inputs so you really can't use the Tape Monitor circuit or attached devices for modern digital sources. However, you can still employ the various DSP options to spread 2-channel analog source material around the room. I do.
The good news. I have a setup similar to what you want to do and it works great! With one caveat - My receiver actually has 5.1 analog Outputs so I can drive up to 6 external amplifiers if I want to (I drive 4). IF yours does NOT (*) we have to be creative in extracting the front two channels from your multi-channel receiver. The obvious alternative place would be at one of the few OUTputs on the back, assuming you have one free to use.
* I can't find your exact manual so I have to extrapolate features.
I see on the SR>6003< there are Pre Audio OUTS so I'm betting your receiver does, too.
A separate stereo amp for the 901's was my solution. I run a Carver AV-406 (5-channel amp) for my 901's in Front, 2 Subwoofers and the Rear Surround channel, with the Active EQ between the receiver Front L&R Outputs and the 901's amp channels. My receiver controls everything and just drives the Center and Surround speakers.
You could get by with just a stereo amp for the 901's. A Carver M-200 is a good efficient amplifier that would have you cooking just fine (2x100W). Run it with the Active EQ between the receiver Front L&R Pre-Outputs ** and the 901's amp channels.
** Front Pre Out; (or VCR or Tape Out if you don't have Pre Outs) >>> Bose EQ Amplifer IN, then Bose EQ Amplier OUT >>> new amplifier IN.
Attach the 901's to the new amp, set its volume to Max and run through your receivers speaker level setup.
*** If you use a Tape or VCR Out you will NOT be able to SELECT the source you use for the 901 Pre-Outs for listening, or else the 901's will not get any sound sent their way. DO NOT USE the monitor switch for that source.
