I don't understand??
You have gone to a company who supplies kit and they have advised you on some kit that is out of your price range and over your budget, and can be bettered by far cheaper options.
So, all in all I can't see what your actually asking then and why you have complete faith in the company who have not stuck to the plan??
Seriously, what projector have they advised?? As there is only one worth considering right now imho.
What is the exact screen??
Why the [censored] have they recommended so many subs?? for a start they are not needed, expensive and will probably be a mare to integrate well compared with two nice 18" subs run in a mono configuration.
Basically, if you want to keep with the installer and keep the kit mentioned you have only one choice, stump up the money.
