I'd like to link two 20' LED light strips together. Each strip comes with a 12v, 2A Power adapter. The adapters that came with these sets make a humming noise, so I want to replace them. Rather than have to buy two new power adapters, I'm wondering if I can just buy one same (but quieter) adapter for both sets. If that would not be powerful enough, could I buy one 12v, 4A adapter or maybe even a 5A for more power?

I have 8 LED sets in total for my project and I want to link 2 together for 4 different places so that would be a total of 8 new power adapters or just 4 if what I'm asking above will work. Please let me know. Thanks!

Yes, you can power several strips using more powerful adapter. Wire two of strips in parallel. You do not need to care about brighness changes, as internaly stripe consist of substrings where LEDs connected in series, thus brightness is balanced.
