hello people I’m slowly despairing… I’m looking for a final stage for my subwoofer, now I’ve read a lot here, zb: that the final stage should do something more than the woofer can handle and that’s where my next problem is the woofer needs 400 watt rms. the sinus live sl a-1500 I like of price performance but it’s apparently not so stable and resilient. the acr man also could not advise me so well because he has nothing there in the performance class. but maybe k Can you help me? Car: A3 HU: JVC BT 1 with extra subwoofer output… Music: Rock, German rock, Pop Price: around 250 euro thanks mfg Harti
