Nops Docteuir...
I can do it myself...!
1)Actually most of carpenters can guide me that not to use lassani for rear shelf...because it can pick moisture in cars,which produce powder...later on this powder end the phatta and cause malfunction to speaker coils by spreading the powder particals to the speaker,when it is playing !!
2)But it is good to use lasani for making enclosures because it makes a difference in bass,and the box is somehow cover from inside....Therefore it didn't having any such type of issue !
These are advises given by majority of carpenters to me,don't know whether they are true or wrong..
And till that time to today,I am going accordingly to this theory..Always make chipboard phatta for my past and present rides !!
But if i am on wrong side then do correct me...!
Best Regards
