Need Advice

Hello everyone.

I am helping a friend put togather a dedicated HT room.
The room size is 23' long by 8.5 wide with a 7'ceiling.
The speakers he purchased were from Polk Audio.
Specifically the RTi A7's for mains, FXi A6 surrounds and the CSi A6 center.

He wants the ability to bluetooth his iPhone and have a receiver that allows duel subs.

Any advice for make and model as well as wattage for this 5.1 system is appreciated.

Thanks to all.

What budget does he have? Does he want discrete sub outputs or can he go with a splitter. Not many programs have any material for two separate subs so a splitter works pretty well usually. The polk need at least 150 watts but will benefit from the subs. Does he lean towards separates or a receiver? Blue tooth input can be had in some models. The Marantz 5005 could work well in a 5.1 setup especially if you bi-amp the mains with two channels each. The mains can use up to 300 watts so maybe a receiver won't cut it but the 5005 is on sale with free shipping.

See this article. It explains a lot about what you need to consider.
