Trunk springs adjust problem
Recently I put subwoofer in my trunk and sound isolation was made which caused trunk lifting problems, because of trunk weight. I have searched forums and found out that I can adjust springs. Now the springs are at first "knot".
Problem is that I could not stretch the springs. Is there any other specific way to adjust(stretch) them or I need to buy spring tension tool and try harder? Thank you for your answers.
