Right Speaker input not working!

I recently bought a Soundscraftsmen 3000A Solid State Stereo Receiver along with a Kenwood KD-3100 turntable.  The issue I am having is with the speaker inputs. It has inputs for 4 speakers.  The two on top are for left speakers and the two on the bottom are for the right speakers.  The left speakers work perfectly fine.  The bottom inputs for the right speakers are the issue.  They will work for about 5 minutes and then it will sound like the speakers are blown out.  Everything is wired correctly.  When I wire both speakers to the left they work perfectly fine all day.  It's the right speakers that are the issue. Check the fuses too and they're brand new. Would anybody know what might be wrong?

OK, it is for one or two pairs of speakers, soooo, try only 1 pair, any luck?

Cleaning contacts can be good, however, playing for a few minutes, then cutting out is not a dirty contact issue IMO.

Speakers, two pairs? Do you have the receiver's manual?

Unless you have a selector up front for speakers A, or B, or A+B, it may be that you are only supposed to use one, or the other speaker outputs, not both.

Often they are for different OHMs, i.e. a pair of outputs for 8 ohm speakers, or, use the other pair of speaker outputs for 4 ohm speakers.

Efficient speakers, high sensitivity? 

I would hook up only one pair of my most efficient speakers, see how it is. Even small speakers from your office temporarily, just to see if it makes a difference.
