Hello community, I am busy with my sub-extension in the luggage compartment ! Since I have the Hifi-System Professional I am completely satisfied with the remaining 10 loudspeakers so far. Since these are already driven by the factory-side Hifi amplifier the sound, for my ears, is really sufficient. Now I would like to feel a little more fullness of the bass, since the woofers under the seats, although also the low bass frequencies are not enough for me At UE2000 I have now discovered the phase Linear RS 2, which looks really good at the layman’s view and is very tempting from the price. Since I don’t get a chinch output from the factory-side radio I have thought about getting this XETEC USC High Low Adapter. My musical taste is house/electric. To the budget – good question – it doesn’t have to come to the 1000€ brand – it should just be the price-performance right! Unfortunately I have no experience in housing and would like to be on a Maybe you can help me and give me a recommendation if the top listed power amplifier is good and which sub could fit well. I hope you can do something with it. Already in advance – Thank you. Greetings Flo
