Hi could u pm me price include pos for saga lmst 4 doors? How many meters needed?

My question are as follows:

1)And also could u advice me which type is the best to put at doors?

2) best to put the big D type on the top section of the door?

3) What about on the bottom part of the door? Which type to out for best effect?

4) what about side of the door? Can I put the big d type or small d?

FYI: I plan to cover all sides of all my 4 doors

TQ

Btw what's the difference between those 3 types? Could u explain the uses/function btw D type and P type?

Which are better for my saga lmst?

I might as well put the BIG D rather than Small d for better sound insulation right? Correct me if I'm wrong?

I'm very interested here might be ordering in few days time as I will be free to wait for the postage at home:)

Tq
