Alright so i have an audio setup that weighs probably close to 100 lbs if not more. I have a 4 cubic foot box i mean come on theres some weight there lol anyways the car sits lower in the back compared to the front with my sub and boc in the trunk. What can i do to fix it? New shocks? Struts? Im no suspension expert. Do shocks and struts come in dofferent strengths? Could i get new shocks that hold the weight up better? Thanks
