Hello Folks

I drive a 99 Civic EX Sedan. I recently upgraded my head unit to a Sony Explod 7705 model which is rated at 52x4 power. I also recently bought through Ebay a pair of Infinity 6x9s 9603i rear speakers.

Can anyone refer a DIY to me for installing these? I read somewhere that these speakers are deep and might come in the way of the trunk rod. Will they fit in the factory speaker hole in the rear dash or do i need to modify the opening?

Any suggestions are welcome.
