Best amp for 4 Sonos ceiling speakers?

Hi Guys,

Recently moved into a new home and there are 4 ceiling speakers from Sonos in the main room.
I'd like to make the best use of them for music, movies and parties :)
What's the best amp to buy for these? 
The specs for each speaker are:
Two drivers (1-inch tweeter, 6.5-inch woofer), 8 ohms, handling 130 watts maximum power, and 89dB SPL sensitivity. Frequency response is @ 44Hz to 20kHz.

I'd love to have a nice bass effect, and loud crystal clear sound.

Also, I'm on a budget and have zero tech savviness haha. 

What amp would you recommend? Would you recommend I add a subwoofer?

Thank yoiu so much!
