Need help with speakers/receiver

[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 Im 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 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 Im 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.

seems like your amp is clipping. it has a protection circuit inside. your receiver is 105w per channel, so perhaps may not be appropriate for insanely loud levels of music. you will need a more powerful amp. and the likes of yamaha will always have atleast a 10% discrepancy in actual output.

im not sure what youre looking for exactly. is your setup mainly for music? then you should go for a stereo setup, without surround sound. are you lacking bass and thats the reason you want a sub? if all you want is it to be loud, look at a professional setup. you get entry level ones and they;ll definitely be loud with big punch. but there wont be refinement
