The size is smaller than the original 4's but the sound is much better. This isn't a whopping system but it kicks fine without annoying the neighbors.

Bermuda deck slid in with any mods. Plays MP3's, sub outputs if needed, a remote included, nice styling (black) red at night, and the most important part has an optional input for iPod .... critical, never need a disc changer again!. Run the AUX jacks through the ashtray and hide them when not using. iPod has an RCA cable that is about 3 ft and you can put in right under the armrest.

Got it all from crutchfield and although the directions were for a w126 is was close enough with some help from members here.
Oh, and the speakers were $78 for all 4, delivered the next day .... not too shabby.
I just ran the connections to the existing fader (mine works fine), but will run direct wires during the winter downtime along with some dynomat.
