Hello, I’m looking for something(!) bass support in my Corsa D. Had asked me about it in a special HiFi forum. Apparently this is too high for them there and a clever answer did not come within a week. Therefore I ask here again. The most important points for my project: – space-saving – “soft”, discreet bass support for the (for the time being) original front system – price performance should be of course the best possible n ACR and I just asked a bit bluntly… Who I talked to (he always builds up the components), knows the Corsa and recommended me after a short conversation either the Axton AB20A or to save even more space the Axton AXB20STP. According to the reviews of the AB20A the small one is really good for his money and sounds exactly after what I need and above all enough for me. To the other, which comes into the RR-Muld, there is unfortunately still not a long way to go. my fear is that the cover over the RR-Mulde starts to vibrate very much. I have to say that I am not a total newcomer in the Ca-HiFi-Breich. Had already installed a sub in my old car in a self-built housing + power stage and a good middle class component system. I built everything myself, which I don’t want on the Corsa, since it would become much more expensive if something broke. Price license h is the installation of the ACR at 75Euro. I already have cables, Hi-Lo adapter costs 20 Euro. Is the price okay, what do you think? MfG, Thank you
