Check the speakers with an OHM meter to be sure that they are not bad. Switch the speakers so that the front is the back and see if the issue goes away. If it does not then it is the amp. It could be the temp sensor or overload sensor

    This is not something that you can fix by yourself. Other than making sure you are in the correct mode, you most likely have DSP(digital sound processing)issue. This is not an amplifier or speaker problem, so in my honest opinion, forget about checking the amplifier and speakers for problems. I might also say that one of these answers, I find it rude and inconsiderate.

SOURCE: Problem w/ Panasonic SA-HT700 speakers

Let me show how to resolve your problem since you are not very good at this system.
A/V troubleshooting 101:
Remember the 2 speakers that you mentioned before that it worked.First,locate the one speaker output that work for you before(ex. front left)you will use this speaker output to connect each one of the speaker and leave the system on either tuner(radio with a proper station=101.3) or a dvd with sound,this way,you are troubleshooting two things for sure A. be sure all your speakers do work and B. your source is working.
After you test all the speakers with the same speaker output which had confirmed the speakers are working,that particular speaker output is working and also your source is working,send me an email and i will show the next step.
However,for any reason,if one of those speaker got no sound from the same speaker output connection,please do not waste anymore time,should take it back to the place you bought it from and get our money back and try to buy the A/V system separately(A/V receiver with speakers in one package, separate dvd player,etc.)
Cheers,

Alright i had a chance to look over things, this is how you are going to hook up the sub. first we'll be connecting the surround sound unit to the sub woofer.
surround sound unit sub woofer
left front: positive (+) <-----to------------->(+) left speaker level in
negative ( - )<- - -to- - - - - - ->( - ) left speaker level in

right front: positive (+) <-----to------------->(+) right speaker level in
negative ( - )<- - -to- - - - - - >( - ) right speaker level in

now that the surround sound unit is connected to the sub woofer you will need to connect the front surround sound speakers to the sub woofer.
sub woofer front surround sound speaker
left speaker level out (+)<-----to--------> (+) left front speaker
left speaker level out( - ) <- - - to- - - - ->( - ) left front speaker

right speaker level out (+)<-----to--------> (+) right front speaker
right speaker level out( - ) <- - - to- - - ->( - ) right front speaker

Alright now that the wires are all over the place and plugged in
turn everything on and see how it sounds. let me know if everything is working as it should. if you need help with anything else or if something does not seem right please feel free to contact me via e-mail or phone

The connection on the receiver would be the sub woofer out. Not a sub woofer out LFE, a sub woofer out with speaker wire connection. From there you plug it in to the top section of the available terminals on the sub you are referring to (speaker level input). One in positive and the other in negative matching what you did on the receiver with correct ends. The speaker connections underneath the top connections is for additional speakers like surrounds to be able to be connected directly to the sub woofer speaker level out for sound. This of course would be for an older receiver connection. I do not think it is possible to convert this connection to an LFE and have it work properly. If the receiver does not have sub woofer speaker connection and only a RCA out then you can try to connect both rear speaker connections from the receiver to the speaker level inputs on the sub and then connect your rear speakers to the speaker level output on the sub to power them. This is an active sub woofer but for some reason they made it connect as if it was passive. I am not sure if this sub is designed for really low frequencies required for movie or if it is better for music.

configure ur PC (both OS audio and third party sound driver) for surround sounds. control panel- sounds and audio devices - speaker settings - advanced - speker settings. so this done. make sure u select the 6 input channel - the button is on the right edge near the volume knob. near the vol button there are two buttons for selecting input type with up down arrow. from that u can select the input type this will be indicated on the top front indicator. but with the 6 input channel selected all selections are preceeded. if u select stereo mode u will have left/ right audio only.
make sure u connect the input right. connect from computer to 6 channel input. main, surround, center and sub-woofer.  connect the spekers to main (L/R), rear(surround) (L/R), center and sub woofer to terminal marked sub woofer ouput. this done select like i said before the 6 channel button. that should do it.

Based upon your description, the subwoofer is just a speaker and is taken from the normal speaker outputs. Run your A channel to the sub and then from the sub to the left and right front speakers. That should do it.
