COLSMITH,
I posted a link a few months ago (can't find it now) that explained that the number of speakers per car was growing rapidly due to the extra customer demands (DVD TV,Surround sound,Sat Navs ect)so it's not just looking at what is presently but car manufacturers need to somhow intergrate all these extras yet at the same time keep these pound and ounces down!
So basicaly weight due to Audio will increase overall going forward in cars but by useing NXT this weight "gain" can be significantly mitigated.
I hope that makes sense
Lisa:)
