Evening together! Unfortunately, the days somehow broke the power amplifier and now need a new one. So far I had connected a relatively old quadral Straton A-200 (2-channel). The front 2 standard speakers of VW (Golf IV) and a bass roller Magnat Killer Bull 300X (280/560 watts) were connected. If necessary two more normal boxes should be added later. It should be a 2 channel again. Can you recommend something to me? Should price be if possible I. (Unfortunately I don’t know) Thank you for any help!
