Hi is a well-known driving teacher and there e often sends people to me who want to put “boxenteller” on the shelf. now I suggested what to hang up with him and he was immediately thrilled! so I need pictures and pictures. of bad installations and accidents like this. writing etc. I can do this myself – tips nevertheless desired. this is a very great driving school so many people will see that too…….if it brings only 20 people the insight it would be great but i ch think that will be many more. this forum I will also “link” here there is simply the least spinner. and friendly tips without “haha du depp”. otherwise no direct advertising on it. only bitle what about :http://en.wikibooks.org/wiki/Car_HiFihttp://www.autohifi-magazin.de/d/48302#http://www.profihifi.de/sites/wooferkisten.htm and keep my tel. number for free advice. thank you for the help! byebye
