DFarr, Great Price non the less.
I got my response back from BSW. there is a difference between the coupe & convertible in the E46 2000-06' Body style.
the difference is in the rear. the coupe has a deck that accommodates the same 6.25" mid bass that are in the front Doors where in the convertible its a 4" mid bass with a proprietary adaptor. the tweeters are also different in the rear where the coupe accommodates a 2.5" mids whee the vert only accommodates a 20mm tweeter.
I hope this information clears up any confusion. these are truly for VERTS ONLY!
