Question What Amp should I buy?

[juanmolero]

Hello guys, so I want to buy a good budget 2.1 audio system for my living room, I was going to buy a regular bose soundbar and a bose subwoofer, but I've read on the internet that you are better off buying a pair of bookshelf speakers, a subwoofer and an amp, so I chose these:

https://www.amazon.com/gp/product/B07FKH9ZDC/ref=ox_sc_act_title_2?smid=ATVPDKIKX0DER&psc=1

So based on the wattage that these guys handle, what Amp should I buy?

What jumps at me is the Polk are rated for 87db, which is low on the efficient scale. Low efficiency speakers require more amplifier power, so I'd want amp close to 100w. Sub is self-powered so that takes care of itself. Amp should also have BASS MANGEMENT, a fancy word it has crossover and dedicated LFE port for sub.

I own and recommend SMSL amplifiers. They are small which is perfect for a desk, run cool and quiet and are affordable too. 50w per channel will be plenty. Follow the link...

Im actually running something similar in my shop. Polk Audio bookshelves with an SMSL amp. No sub, but I don't need one for that PC. For my main workstation, Im actually using studio monitors from Presonus which have a built in amp connected to a Shiit Audio DAC. You could go that route too.

So wait, I already know that the sub is self powered, but, doesn't it need to be connected to something like a receiver, so the receiver can control how they sound?

Let's say that I buy this receiver:

Where would I connect the subwoofer? Since all I can see on the back of the subwoofer is a white and red RCA connection and that receiver has a weird port for subwoofers, again, I know nothing about this

Would this one work?

Let's say that I buy this receiver:

SUBWOOFER OUT TO LINE IN.

There is only one set of jacks of that receiver that says SUBWOOFER, nowhere else.
Then while sub says LINE IN, that's also your ONLY set of input, you have no other choice.

Really can't get confused.
