im so sorry to hear that.. i know exactly how you feel , several months ago i was hit for 2 15'' kicker L7 subs with a custom box and 2 amps. a kicker sx1250.1 and a kicker sx350.4.. a total loss of $1,237, man i was furious.. i was out for blood but then i realized 2 IMPORTANT things..
1- if i would have caught them i would be in jail for murder and away from my family
2- what goes around comes aroud (( god dont like ugly ))
they put my mind to ease a lil but till this day when ever i think about it i get so f-ing upset i want to give every car theif a nice ((( curb job))).
then slam my trunk on his hands a few times for good luck...
