it makes a significant difference in sound as well as road noise. If entertain any hifi car audio upgrade sound deadening the doors and as much of the car is essential to better sound.

my car is going in next week for a full audio install. i saw some videos online on how to remove the door cards and figured i would do the deadening myself. Very simple job and i would take more care than anybody else.

i prob used way too much but ended up with two layers of deadening on the doors with a acoustic foam layer on top.

Land rover includes one 6x4 piece of deadened on the door. does do much.

one of my concerns on the new audio system was the road noise. i needed to cut that down for me to even the differences in the new audio system. it is noticeable quieter in the cabin. i only deadened the doors and trunk space. Audio shop will be doing the floors once they start pulling panels off


cost me 150 bucks in material and about a day.
i broke up the job into several days. a door a day. about 2 hours per door

 

the meridian 700 watt Surround has 14 speakers and a sub. i believe the 400 only has 10 speakers.

you lose the mid range in the front doors and center channel and possibly the rear trunk speakers

 

My dad has a MB with the Burmeister system. The top Meridian system in the Defender is nowhere near as good, just FYI.

I would say the high end 27 speaker (?) system in the Full Fat Range Rover or RRS Autobiography (or SC) with the $4500+ Meridian option... is about as good as the Burmeister (it's identifiable by having speakers in the headliner aft of the sun visors).

 

awesome information. Thank you. Now I just have to find that video that tells me how to remove the panels…

 

I have it bookmarked. Here you go:
I'll be referring to that video when I replace those cheap door speakers and add sound deadening
