Wetsounds amp quick connects my problem?

Some of you may have seen my post a couple weeks ago I was having trouble with one of my rev 410 speakers not working when connected to my sd4 amp. I ended up swapping the connections and the problem went to the other speaker. The speaker would work off and on intermittently so I thought maybe I should check the connectors when I move the connectors to the other speaker wire the problem went to that speaker. So I think I have found the problem at this point to be the quick connectors on the amp. it seems like they're not getting a good grip on the post or one of them anyways. The two good connectors work no matter which wire they are conncected to or which channel they are hooked up to on the amp. Is there anywhere I can order some more of these quick connects or possibly get some from wet sounds? I looked on the website and cannot find them thanks.
