i have the pioneer three speaker system, my door speakers are 'Pioneer TS-A467R' and I guess I slammed my door to often and the middle piece popped out of its socket. I tried playing music out of it with it out but with no luck. I then checked the wiring both in front and behind, all good. How do I mount this middle piece back in? Will it work if I do? And does this require soldering, glue or what? It costs 44 bucks on Amazon and I'd rather both save the money (poor college student) and learn more about my lovely Porsche 944
The broken speaker (losing middle piece I described)

My other one that works on the passengers side
