i have reg cab dodge ram with my system in it thats in my sig. now, would it be worth sound deadening this truck. the problem is that to even get it it to sound loud i have to open the dam windows, yea, it was a cold winter. i know it will keep more bass inside the car and keep the noise inside so i dont bother other people but, i have to open the windows anyway. i mean, its a huge difference. thanks.
