Hey guys, I have just had my car system installed (4 door speakers, amp and sub) in my LPG VE commodore but now there seems to be a few problems. They told me about the first problem when I rocked up that being as they said the car makes 5 horn noises when locked. After further investigation I realized that it was a door senor. Then seconly I noticed when driving it home the stability control was off. When I tried to turn it back on it didn't work. What should I do? Obviously I will call them up tomorrow about it but should I take it back to them just to fuck it up? Or should I get them to pay for it to be fixed at a dealership? On a side note I wasn't too impressed with the install either I can take some pictures if you guys are interested.
