If you bought directly from Alpine and not through me, I have very little if any leverage - that is the benefit of buying through me but I'll bring it up. I also can provide details of the install and suggest additional parts that are not included in their instructions. They DO have a great product but sometimes lack in following up with customers - call them if yo have issues with them - John is old school and seems to deal better with phone calls than email 714-379-8066
