Howdy dude,
Well all I can say is that when the install is totally fixed and complete it will be one hell of a system you'll have. From what I heard the sound quality is really good - and will be even better if you get the 4 channel amp to stop over-driving the speakers. Although to be honest it sounds pretty damn good anyway without it. The volume is another matter altogether - you are one crazy dude that will be deaf very soon if you use half the systems capabilities.
You are going to have one cracking car on your hands very soon - when the install is finished, the defi's are in and the wheels arrive next week. It seems you mod your car as often as I clean mine.
You are a true NUTTER - but we love you really.
Dave
