How much will a home theather system cost for me?

-i would like really loud, nice sound, really loud, full of base mainly, like enough like enough that people put in their cars

would speakers and subs would i need to get, and could you tell me some that i could get from like bestbuy or futureshop or something , i live in vancouver bc,

i have a budget of 4000$ and i just like a simple not very expensive led projector that ive found many and only cost like 500-1000$ and have 3d,

so 4000$ is my budget for projector and sound system, so what speakers and subs should i get and reicever , the inches of the sub etc, thank you, and any projector led plz suggestions thank youI would recommend you go online to Home Theater Magazine and read the reviews on speakers and tv. Staying with name brand for better quality and reliability. For receiver I would recommend a Pioneer, Pioneer Elite or the Onkyo. For speakers, Definitive Technology, Energy, Infinity, JBL, Focal, Klipsch and Polk Audio to name a few. I would demo them at your local retail store and bring a cd to listen to and only listen to one song. I have used Pioneer Elite and Onkyo receivers for well over 30 years had have had no problems. For Speakers Martin Logan, Infinity, JBL, Energy and Klipsch, again no complain from any of the speakers. Hope this will help you out.
Klipsch reference series loud speakers - 2 on each side, 2 at the front, woofer, and center $5000

Denon or Yamaha 7.1 surround receiver $2500

bright LCD projector $2000

forget the big box appliance stores like Best Buy, and find a shop for videophiles
