So people, after I finally have steel rings for the TMTs and have everything installed, I want to write a little report. 1. Problem in the convertible is clearly the bass and that much volume simply “flys away” through the not existing roof. On the bass is still working (also with the Flex^^). Therefore already powerful TMTs have to come. I decided for the Ciare CW 162, because these are also relatively cheap to get. The doors are of course properly insulated. (I have re-edited on the inner sheet, now the door board is only not going on with much force The fixing is of course still worthy of improvement, because the Golf IV convertible holders are a bit unstable, but if I wobble on the TMTs, including steel rings, the inner sheet rather shakes than that the holders give in, so I think that’s OK. Since the holders are open, I made a case as closed as possible with bitumen so that the TMTs play on the inside sheet. I’m very happy with the installation and the volume The steel rings have already paid off for the MDF rings before. (Thanks Doom). A big problem was to get the TMTs through the steel rings, because the magnet always wanted to cuddle with the steel ring 😛 But see a few pics here, constructive criticism is desired, even if I don’t really have a bock anymore to remove the door board An Audison SRX2s with 180 watt RMS per channel serves as the final stage for the TMTs. http://meingolf3cabrio.de/wbb2/attachment.php?attachmentid=8650http://meingolf3cabrio.de/wbb2/attachment.php?attachmentid=8684http://meingolf3cabrio.de/wbb2/attachment.php?attachmentid=8685
