Scott:

First thing first, thanks a million for your response. If I am near where you are at, I would love to bring my car to you. But I am not in the states and I am hesitated to spent money on technician that doesnˇ¦t know the complicated 11 speakers system!


You are right, how do I know. Well I am only guessing. Mine is a 92 early model W140, 300 series. I don't think I have the bose 7ch amp as I don't have the bose label on my speaker grill nor can I find that BIG black thing which I think is the 7ch amp unit.

Secondly, I think itˇ¦s the speakers as currently my speakers do make sound just that its mashed or cracks or whatever you call it. I would think if the amp were gone, that speaker would not make a sound. Right??

My question is this:

1) Am I right regarding my case for having, or not having, the 7 ch amp??

2) If I do have, do you have procedures for testing which one is wrong?

3) If my amp is faulty, can I replace the amp and speakers to non-OEM, say Alpine, but leave the head-unit in place? If so, recommendations???

4) Do you sell OEM speakers?

Thanks in advance.

Cheers
