Hello together, in my convertible I want to help sound a little bit. However, only to a small extent, so only a light bass support and maybe another front system – if that is worth the effort at all. Currently the gamma is in it – and that should stay it. I like the original optics very much and want to keep it if possible. Then maybe will use either the mobile phone as MP3Player – or a separate MP3Player as music source. I dac ht now just to bring in a little more fullness by means of a simple active sub. I looked around a bit and find either the Pioneer TS-WX11A or the TS-WX22A quite nice. Both lie with around the 130€. Wouldn’t be a big effort to install that accordingly. The WX22 is certainly the more powerful sub, but with a height of 11cm probably too big, for under the seat. So had to wander into the trunk and would probably lose a lot of effect accordingly. The WX11 has a height of 80mm – could it fit? I’ve searched the whole MT and it was partly recommended. Did you have a closer experience with this thing – and above all, someone knows if the thing fits under the seat? Alternatives to that? Would I be happy about a few tips. But please don’t suggest 1000€ conversions, because if I want to listen to music, I’ll take my A4 It’s really only about a small sound improvement on simply The way. Greetings Jürgen
