Well I have my car booked in for Tuesday to get the Alpine HiFi upgrade done on the sound system. I purchased the HiFi kit and 2 x door surrounds from Schmiedmann in Denmark (had to return original shipment as tweeters were damaged - all good now new kit shipped back to me). I saved a lot of money purchasing the kit this way.
I am getting ripped off on the install at the Stealers but I have no choice if I want the warranty - it also has to be coded once installed. The down side of Perth only having one Stealer - you constantly get ripped off.
Will let you know how I go and if it is worth the $1,000.
