Thanks foxp44 it was well worth the effort , putting the sound deadening in makes a massive difference as there's no vibration on the outer door skin which would over time create rattles, the inner acoustic foam gives it a top end stereo sound all for less than £200. At 1st I wasn't impressed with the sound until I dailed in the equaliser settings , it sounded very tinny ( to tweety ) not much base , hope this helps cheer
