Okay thanx so far guys. It's this amp http://www.extremeaudio.de/gb/audio-system-helon-90001-mono-verst-228rker-11500-watt.html
- I am aware that DD and AQ are closely affiliated, the price however differs a bit. I agree on saving up for what I really want. Now, the problem is that I allready have two 3518f D2s. This is an "older" version, so I really can't find anyone that sells this edition anymore. That's why I started looking for 4 new subs. However, if anybody got two of the 3518f and are willing to ship I'll pay good money for them!
