Yep. 13.
Looking at the front dash speakers from outside the car in a certain light, it is obvious they are the El Cheapo brown paper variety, and are smaller than you would find in your kitchen mantle radio. I figure nearly all the sound is coming from the front of the car, the way the Saab intended, which I like. So the rears can wait for the moment. I want to change the front set, including the front doors. The little tweeters might be doing all the work judging from the sound. The rear amp in the boot is massive to be sure. But put the fader to the back and there is no volume to speak of. That can't be doing the right thing back there, surely.
So getting the speakers out of the dash needs a few tips, as the clips will surely snap? Do you attack from above, or below?
