I just reinstalled my subs and within seconds there was a problem, about 10 seconds after hooking the negative up to the amp, it started making bass. My car is off but i have the key turned so i can eventually turn on the radio, when it randomly started thumping. The Radio is turned off, but sub's are making bass, i just dont get it if the radio is off where is it getting the signal to make bass? Its just really random mid-range thuds that continuously happen like its playing to some non-rythmic beat. Are my wires mixed up, or is my amp messed up, or just something stupit i over looked? Im hoping one of u guru's could help me out. Please guys im lossing sleep over this.
