Hi,
I have just had the alpine kit installed by a local car audio specialist.
To cut a long story short there was no sound coming from front mid and lots of noise from the tweeter, so I look it back to him. It turned out that he had put the input into the midrange wire, the tweeter into the output and the midrange into the crossover input. The system seems to sound good now that it is correctly wired, but, what damage would this likely to have done to the tweeter and/or crossover?
Just to put my mind at rest if anything else

Kevin
