My car: '98 A4 Audi

I'm Replacing my front driver door bose speaker and passenger side while I'm at it if I buy these "Infinity Reference 4032cf 4-Inch, 105-Watt High Performance Two-Way Loudspeaker (Pair)"
@
The speaker I removed is a bose "8D0 035 411 C" and needs replacing.

So will the speakers I'm looking at buying be able to work with the rest of my old bose setup since I'm trying to avoid replacing everything? I already fixed my rear speakers with silicone making them sound close to new again but this driver door speaker needs replacing since nothing is noticeably wrong with it visually. It just sounds bad randomly at normal music level and it's really noticable when it's turned up high.

 

Looks like if I do this: S4 Bose Speaker Replacement Writeup It'll work... I feel like deleting thread but I only see how to edit text not delete thread -.-'
