If they are the stock speakers, I made sure that the main speaker cone "slides" freely from the tweeter. I used a strip of paper to clean the gap between the tweeter and the brass sleeve to remove any dirt that would cause the main speaker cone to "hang" and cause distortion.

I have a 1998 S70 GLT with 130k miles. It is "blowing out" some antifreeze from the weep hole at the bottom of the intercooler assembly.

Does that mean that the turbo has developed a crack or seal leak in the internal cooling?

Thanks.
