Default Help strapping Sundown amps

Been searching for a while with no luck. I am tying to strap 2 saz-3000d's together on 4- d4 sa-15's. The amps do work individually but I know they can be strapped and I would then know the gain matching would not be needed and output should be better.
The subs are wired down to 1ohm per pair, with the positives going to (+) terminals on the master and the negatives going to the (+) on the slave. The (-) terminals are wired together between amps. The sub out from the deck goes to the in on the master, and a mono rca goes from br-out on the master to br-in on the slave.
The amps play but i am getting a feedback noise (whine) through the subs and the slave eventually goes into protect. I do not have any problems like this when playing separate.
Anyone have ideas on how I can get these to work strapped?
Thanks

I see now that I put this in tutorials when i wanted it in general wiring help. Since it is here, how about someone post up a good amp strapping tutorial with any known issues that could cause problems if not done properly? Thanks again.

You have them strapped @ 0.5 (0.25 each). Rewire your subs.

when you strap them you dont have to line match the amps.you only have to set the gain on the master amp ,the slave amp doesn't have to be set.

Thanks for the reply. I will rewire. Guess I did not understand how the ohm value would divide. Thought it would end up at .5 per.
