Hi everyone, new guy on the forums.

I recently bought a used Sony CDX-S2000 to use in my BMW e34. The problem is that it seems like it really lacks speaker power. I have to turn the volume up to 3/4 to hear it, and to maximum to have a comfortable sound level. At 3/4 the sound is pretty good quality (although very silent), but when turned up it gets really raspy.

As some of you might know the original e34 speakers only take + from the deck, negative is wired from somewhere else. Could the Sony deck have a problem with this?

The Pioneer cassette deck I got with the car has no problems with it what so ever, and the sound is very clear and good considering it still has the original speakers.

Does anyone happend to know how many OHM's the original speakers work on? AfaIk the Sony deck is designed for 4 OHM speakers.
