So the speakers in my 79' 240D are... well sub-par, fuzzes out very quickly picks up no bass what so ever.. what are my speaker options for the car size wise and power wise without having to change the headunit.. i just want a fuller range of sound, i'm also working on hooking up a small sub as well and need help with that.. so far ive come up with installing a LOC and running the sub to s seperate amp but i dont want it to hit THAT hard im not looking to break glass.. just a good umph here and there lol.. anyway.. speaker sizes and good replacment speaker options as well as extra speakers?.. how did you do it where did you hide them etc. etc. i want this car to look as stock as possible because i love the way it is now.. i dont see a problem merging new technology into old cars but keeping them classics. k thanks
