Good Tach! Got my stuff in it now (see below), it’s been going on for about 4 weeks, and it seems to me that the whole story gradually starts to drag on. What was definitely and not at all at first!! In order to get to the origin of the troubleshooting, some facts: The battery can’t really be, although I don’t have a cap and also the volts yet, but light etc., it doesn’t flicker, even with SUB-breeds not… That the Rainbows are not sooo dolle after all , I notice by now, because the HT gives it all back, but also a tearing (with nickelback it is quite violent, or RW ́s “Rock DJ”, there comes the bass hit through to the HT, with other things you can hear it again less to hardly). From the SUB comes clean, it is the FS (my God, hopefully not in the course of teaching….) What can be the cause ? The installation is so leveled that after a week the amp was set halfway, and until then God does not know Boom-Car has played. It is surprising that even at low volume (or just then….) it can be heard. I would have suspected the admittedly not optimal mass point (had no Thorx ratchet for the belt point). Or the next makes the greaves because maybe only 12.5 volts arrive there. Or only fogging sin: the door plate is not 100y free behind the FS, it protrudes a little bit into the opening, but without contact to the speaker basket ! Or, does that have anything to do with the 2 volt output of the radio to do ?? Therefore the basic request for HELP from a distance Oh yes, car is a Modeo V6, the LiMa has 120 Ah, and the battery is reinforced ex factory, has 96 Ah, cable 16 qm, may well be enough for a Q24….
