I just picked up an 05 Magnum with the 288 watt 6 speaker Boston Acoustics system. My dash speakers have rotted foam and sound terrible. Can I simply unplug them till I get around to replacing them or will it cause any damage to the factory amp or any other issues? Also about 10 seconds after a door is opened or closed with the key off I get a click/pop only from my left dash speaker and left front door speaker, has anyone else experienced this before?
