Good afternoon. First of all, I’m a beginner in Car Hifi. I’m technical but I’d say. The following I’ve been running a Continental tr7412ub-or for a long time. Does everything work great without problems. It’s also simple crunch boxes installed. Medium and tweeter. After a few months I have the problem now that by retrofitting the pioneer ts-wx130ea active subwoofer the radio runs out again and again. So with normal bass and medium volume everything is OK. But you get something up, be it bass or the volume itself…. Fupp Radio off. Goes straight back to it but it sucks My guess is that the SUB pulls too much juice and the radio doesn’t like it anymore at the moment? But the active subwoofer is active. He gets his current from ignition plus. Putting the SUB directly on battery is not a good idea, which pulls me then empty or? Mass I have directly from mass point on the body. All bright best greetings.
