I have an MP40 its excellent excellent sound with the standard speakers due to DSO, quite easy to install once you have the right bits (see mikeythemini) just make sure you put the ariel in the ariel port and no the remote or it won't work
I followed the FAQ's and did it myself apart from the embarrassing wrong hole saga (easy done I'm told as it goes into the remote one much easier than the ariel one) a thirty minute job really. Looks nice with the mini interior.
