I recently installed a single 12 inch in my trunk. I believe it is connected to the original subwoofer that came with the car and to the original stereo system. At first it sounded very nice but if you really listen to the music, you can hear a ratteling sound coming from the rear of the car. I believe it is from the original subwoofer cause when i placed my hand on the speaker it stopped. I bringing the car back to the dealer whol installed the speaker to see what i can do about it but i was hoping that anyone else hs some suggestions. Would it be btter to disconnect to aftermarket subwoofer with the original????? I thought connecting them together would be great for a good surround sound.
Any suggestions
