You are right. Local shops do usually do a better job then bigger stores at installing. Unless you have a good store to deal with. I used to work at circuit city and know the installers pretty well. They installed a python alarm/remote start on my old car, several remote starts on my parents cars, and there going to be seeing my 3 next weekend. I have never been unhappy about there work. As for the trunk popper if you set it up you can wire one of the extra outputs on the unit to the trunk. Any good installer would be able to do this. I dont think circuit city would be able to install a trunk popper though. You would have to go to a local shop. DEI makes the best stuff. I bought a viper 791xv for cheap online and im having it installed next weekend. after the install it should only cost me 300.
