i have a 96 jeep grand cherokee laredo and i need a suspension that can hold more weight at the back of it can someone please help
Are you looking for a lift, or just a stiffer suspension? You could add an airbag system to compensate for load. You would likely have to order custom springs for the rear if you do a lift and want additional load capacity.
without know what type of vehicle you own its impossible for us to help you as same car year to year can have different reset procedures. Year Make Model and Engine could get you the help up need
Whoever installed your amp must have broken a wire to the alarm box in the trunk. Car info would help on this.
maybe you should just get a new one
