Help with speakers/stereo

[Woolysworld]

Well here it goes. I like listening to my rock and roll at insane volumes in my house. My stereo shuts down after a point when it gets to crazy levels. So what I have is a Yamaha RX-V465 AV Receiver 525 watt (105w x5)
I HAD a practically new pair of Polk Monitor 70 series 2 Tower speakers which were rated at 275w, I sold them last week. I have a Bose center speaker which I’m not sure of the watts. I think its 200w but when I was having problems I disconnected the Bose.
So now I bought a pair of Klisph Reference Dual 8” Floor standing speakers 600w peak 150 w continuous and also a pair of Klisph Reference 5 ¼” Bookshelf speakers 340w peak 85w continuous for the rear/back of my living room. I bought 12 gauge copper wire and I also bought a 5” electric fan for the receiver which is in a stereo cabinet. (I cut the back out of the cabinet where the receiver is for air to escape. So now I’m thinking of adding a sub.(Heard that may also help with my issue, not sure though) So on top of my issue with this I would also like some input on which one of the two subs that I picked to buy.
1) Polk Audio PSW505 12” powered sub 460w
2) Klisph SW-450 10” 450w.

You may find the Klipsch to be louder than the previous Polks because the Klipsch are more efficient.

If you have Klipsch reference speakers why wouldn't you get a reference sub ? An R-12SW or an R-10SW? It has been designed to work with the reference line of speakers....

It's the cost.
