I bought this subwoofer in the store as a result, connected it clearly according to the instructions. Powered at a high level from the front speakers. Well, to be honest, my old Sony xplod, which was already 9 years old, played much better. There was more bass, they were cleaner. The amplifier gets very hot here, the settings are turned out by 2/3. Not very happy with the purchase. The stock speakers play loudly at zero settings, the subwoofer feels lacking. Solaris 17 car.
