front door h/k speaker retrofit (how to)
Edit- so my installer says to keep these HK's in case I sell the car or trade up. However, if someone wants to pay $250 I will do it. That will cover USPS Priority Shipping to USA or Canada. All the speakers are brand new, I just bought the car last month from a MB dealer with only $6k miles. I can provide a copy of the receipt so you know these speakers are brand new. They sound incredible, MUCh better than the speakers in the model w/o the sound package. The sound package was like $3-4k so $250 I think is a great deal. Let me know!
Thanks,

I'm positive I plugged the speakers in properly and yes the speakers are functional, just not in my car, apparently. 
Could this be speaker polarity?
Found this online, "You have the speakers wired out of phase. The speakers are cancelling each other out. You need to reverse the speaker wires on one side of the car. Do not reverse the wires too all 4 speakers or you will still have the same problem. You have them like this.

I know this doesn't seem like it would cause any problem, but it makes a big difference."
I don't understand how that would happen though if everything (connections) is OEM.

Shipping is absurdly expensive, but time is valuable. I would get 20 clips plus the two locking pins for the front doors.

The only "locking pin" I know of is the square clip that is revealed once you remove the black surrounding trim around the window of the front door. I had the dealer replace the wood trim on the driver-side door under warranty before and they did not replace this clip. On the other door, I tried removing it and gave up and just broke it off.

Anyway, I found all these instructions from Akadan, Bill, VicViper and many other contributing MBworld, but I'm still not entirely sure how will I be replacing the tweeter since the housing size will not fit (Kappa Tweeters will be way bigger than the OEM, right?)
Still a bit nervous here since this is my very first speaker retrofit job. I took out a stereo from VW MK5 previously to attach an aux cable, but never did anything to the wiring of a car.
This job will requires me to:
- Open up 4 door panels.
- Use a tremel to sand all the previous fittings.
- Drill the holes using a 1/8" drill bit or smaller.
- resolder all the wiring.
Is there anything else that I should be aware of before tackling this retrofit, especially on how to do the wiring specifically?
