i dont see why your not getting this. alot of work was done flat rate... this is common buisness practice in alot of the industry. Were not doing repair work so its pretty hard to sit a hourly value on stuff. whats the book time on installing a turbo kit where nothing fits correctly? whats the book time on painting and smoothing all the interior panels/? whats the book time on building the sub enclosure? were not a stereo shop... as far as the cost of the enclosure, i got a quote from another shop owner were friends with, then i maked it down quite a bit. hourly rates are hard to quote. theres a few things where we've alrleady got an idea on what kind of time to quote and those are hourly, but thats it.
