So at the weekend, me and my mate installed a JBL sub and amp into my car. IT was a package thingy, sub, amp and all the wires included so all we needed to do was wire it up which we did and it all looks great. Since we installed it I have noticed that in the dark my lights come on automatically and turn off in day light!! So the weird thing is Ihave an 03 plate 1.2 16V dynamique, so why is this happening? have i installed it and activated i light a sensor??? or something else??? opinions and experience welcome
