Sorry I explained badly, when I said 3 I meant each side front. Yes I have 2 in the front dash, 1 mids on each front door, 1 tweeters on each front door, and 1 seaker in each rear door. So I think pretty standard setup.

As for this amp, I put my hand right down there, its empty, I found this thread on uk x5drivers forum BMW X5 • View topic - Where's my amp this done the trick, so I think on some UK models the amp is somewhere in the TV tuner box.

Sounds real nice too, and such a cheap upgrade, as I had the amp, sub, low level converter and all the cables from a previous setup.

Now I need to figure out if I can get a gain control into the front cockpit, as levels vary so much depending on the source and recording levels it would be nice to be able to adjust. Although its a pretty cheap Mac Audio (mp2000) amp, so not sure I can do anything.
