Need Help with stock harmon/kardon speaker system

In my 2001 330xi my subwoofers have stopped working. At first what i noticed was a popping sound coming from the subwoofers and then the next day they didn't work. I assumed the amplifier was failing but i bought a new one today and nothing has changed. Im sure the speakers themselves aren't busted. I want to know if there are any connections that i should check before giving up and getting an aftermarket system.

The whole HK brain is behind the driver's side trunk panel. Open up the trunk panel and check that all the connections are ok in there. If not, it very well might be that the speakers are shot.

The easiest way to test for blown speakers is to disconnect them and test the ohm reading across the terminals. I believe the speakers are an odd 3 ohm or 6 ohm rating....should read somewhere around 2 ohms up to 8 ohms, anything except wide open or shorted.

Speakers will crackle or pop as they are burning out. Amplifiers tend to do the same thing so the easiest way to test is to check ohms or hook up separate speakers temporarily to test the amp.

Hit up the classifieds on this forum. You can buy a coupe set up and just remove the speakers. Either that or buy some 6x9 speakers that match the right resistance rating and pop them in. There's nothing special about them.
