Good evening friends of the nice sounds, I have here a little problem. Should a new radio install, after that fell on that one of the rear speakers was defective, so 2 new speakers were worried. Now however, completely the bass is missing. Radio is such an ultra cheap China 2 Din touchscreen thing – not the “deure” Android, but that really cheap. As far as I could find out it should have 20 watts on 4 channels. Whether by RMS or top is meant to be guessed. Speakers are Kenwood S6966, and I have to say the heights and how clear they are is really a very good increase compared to the original 6×9 in the hat rack. But what I’m surprised about is that there is no bass. A base drum in a metal song sounds like someone cut on a piece of wood. You can hear it that there should be something bass moderate, but that’s not a bass. Cable + / – I’ve already tried on both of them. Loudness on radio makes louder and the rest of the original loud sprec The sound of an old amplifier/amplifier is connected to one of the speakers and the bass is turned on – brings so much, that you can say “yes, there is more bass than with the Without speaker”. But that doesn’t sound like bass but rather as if something is going on. Am I right in the assumption that the speakers are somehow broken? How can I still test them so that I can exchange them?
