Need New Amp for House Sound System (with map)

[FourTwo]

Hey all, thanks for taking the time to help.

I want to buy a new amp.

I was looking on Amazon for a good but low-cost amp to replace my shitty goodwill amp that I’ve had since I was in college. In doing my research, posts from this forum keep showing up in my google search results, so I decided to join up and ask for help directly.

I want to do one of the following:
Option A) TO REPLACE THE SHITTY GOODWILL AMP/CD-PLAYER/RADIO/RECEIVER THAT I GOT FOR $20, for a much better quality amp.
Option B) Change the overall layout by changing the order of connection
from: [RCA 4-input switch] -> [Amp] -> [5-zone R/B Speaker Switch],
to: [RCA 4-input switch] -> [5-zone R/B Speaker Switch] -> [Amp]+[Amp]+[Amp]+[Amp]+[Amp] (an amp for each zone)

If I go with a single amp (option A), does anyone have any suggestions?

If i go with an amp for each zone (option B) does anyone have an opinion on my using these?:
Amazon.com: Lepai LP-2020A+ Tripath TA2020 Class-T Hi-Fi Audio Amplifier with Power Supply: Home Audio & Theater

Ideally I want to spend under $100 on the amp situation.

Speakers I am running are:
Zone 1 (gaming computer’s speakers) cheap Logitech 2.1 with own amp.
Zone 2 (livingroom ceiling) shitty Sony speakers from goodwill
Zone 3 (bathroom/shower) generic decent-quality speakers
Zone 4 (kitchen above sink) Bose Acoustimass (Believe me I know Bose sucks, but I got the pair used for $8 and it impresses morons who I show off my kitchen to)
Zone 5 (outside on deck) Insignia brand Marine/Boat water resistant speakers, mounted under roof overhang.

Someone IRL told me I need to know the wattages of the speakers to buy amps. But in the case of Zones 2, 3, 4, I cannot find this info. (Also f*** Bose for not posting their wattage info)

Here is a map of my current setup:

I designed and installed a grounded, shielded steel conduit network shortly after buying my house. It was optimally placed so I could later run speaker wire to every room. Most/all speaker wiring runs through it. There are also some shielded Cat6 cables running through it.

It would be ideal to know both wattage and resistance of the speakers in question. However it is unlikely you will damage those speakers at that low power level. If the speakers are low ohm (unlikely) you could damage the amp if you are running only low ohm speakers.

The most likely problem you will have is that the amp will not be able to power more than one pair at a time. I don't have any personal experience with that amp so I don't know how beefy it is. Nor do we know how difficult your speaker will be to drive

OK, first off, that's not a shitty amp. Its worse. For one it's not an amp. If the picture is correct.

My initial thoughts on this are, if your budget is only $100, good luck. Have some patience, save up $500 and buy a multizone receiver. This would give you ample power to run almost any speaker. After that....

Upgrade your speakers to something a little more refined.

Most people who own higher end gear, started out with "shitty" stuff. I know what it,s like to be on a budget.
I believe that's the politically correct term for "broke".
I have a shitty pioneer HTIB that I still use in the bedroom, cause its better than nothing.

Not having anything to hear music on at all, that would be shitty.
