this thread was very interesting.
I must admit that some of you had very valid points, i myself understand that 1k for that work is probably a bit much, i also know that shops love to **** you any chance they get, i have a bimmer and i always call and get a ballpark range and the first question out of their mouth even when its a quote for equipment is for what type of car, at first i used to ask them what for, its a headunit, not install im asking about.
then later i realized they were sizing me up so i alwasy call and get a quote and when they ask what type of car i say honda, then when i visit the shop and they quadrouple the price aftering seeing is a bimmer ill tell them i spoke to someone last month and they said it would be this much.
all in all, dealers and shops are like hustlers, i have had my car rewired 2 times because shops did shit for jobs. i realized i could do a cleaner job so i learned to do this and now im finishing up my install. Its a cleaner install, wires are cut and insulated, proper fuses, proper grounding, heatshrink , proper connectors.
All in all DIY, this forum is a wealth of information, you will learn so much! it might take you a while but you will learn how to do the install and beleive me , if you buy all the proper install components and draw schematics and plans accordingly, you will make it all work and you will be very happy you did it yourself
