Hello guys! Here’s what I did: I installed in my Audi Convertible BJ94 in the front of the DLS loudspeaker, with the extra tweeter sitting next to it, everything in the original condition – nothing was sawed/enlarged on the amaturator board so that the speakers fit there. This should definitely stay that way! These also hang on a DLS amplifier, which was absolutely necessary with the performance-hungry speakers, because on a normal radio, there were no satisfactory volumes. Yes, it is also a subwoofer installed, behind are also loudspeakers, as well as a decent MP3 radio delivers the music, so that no one has to convince me, what decent to do with it. I got a lot of installation help and help what was missing to the already existing DLS front speakers (much:-))! Now one of the 2 DLS loudspeakers (not the extra tweeter) is a bit defective(sounds bad at volume). If I now just take the 2 front against new ones , which of the parts on the http://www.dlsmobil.de/sites/home.html would fit in without any conversion work? Didn’t the car have there for the next four days anyway, so that I can’t measure again quickly now. And now my last question: I love to hear very loud, which probably killed the one speaker. Which companies build even better and more level-resistant loudspeakers, which also fit in there so easily? Satisfied Because I am with the whole system! Thank you for reply!
