Under dash twin speakers

Well, I purchased a bracket to mount the twin speakers under the dash. Has anyone got good info on what speakers they might have used? And what is the wiring sequence for a factory radio? Are you using jumpers from one speaker to the next? Anyone got pictures?

I think you will find that this bracket was designed to mount Dual Tweeters as apposed to dual coaxials or the like !! I have kick panels w/ 4" speakers and 6x9's in the package tray !As soon as I get a New Head Unit and power supply,I'll be putting the tweeters in !!
