1993 lincoln mark viii rear speakers

[BrooklynMark8]

I blew out my orginal speakers and bought a set on ebay. After installing them, I find there is much more bass in the sound. the seller sent me 2 other speakers that go in the rear by the larger ones and they are about 2" round and about 4" deep. I didnt have these in the rear at all, and I do see a "punch out" in the insalation were they would go, but I dont think there is wireing to connect to them. Can I install them and splice off the 4x6's that are there? Are they some kind of "tweeters"?

They are the tweeters that are included in the JBL system. Since I am electronically chalenged I'll let someone else tell you how to connect them.
