When you say "add more power" what result are you seeking? Louder ... better efficiency from the speakers ...? Are you having to change the level of Left+Right versus Center to equalize them?

I have the Yamaha rx-v575. Love it, however, I have Polk Audio RTi A5's in the front and a CSI A5 in the center. I would like to give them more power however, I am having a hard time finding info to read up on how to do that.
I'd like to add an amp I guess to add more power for the front.
OOPS, I didn't see this second page of replies.
The CSI-A5 appears to be matched to the RTI-A5s, but in my experience, the Center channel needs to be as capable and full-range as you can get. The Center channel does the lion's share of work in a movie: dialog, sound effects, some music, sometimes all three at the same time. Maybe the next model up of Center speaker will help you.
Looking at Amazon, it looks like the RTI-A5 woofers only go to 6-1/2"...? Despite those being towers with bass reflex (?), I wouldn't trust those to go down to 40 hz or so for solid, confident movie bass. So on your RXV575, I'd set the speakers sizes (L, R, C, SL, SR) to "small," which is a misleading label. It really means
that instead of sending full-range of frequencies to those speakers, it diverts bass freqs below the bass crossover frequency
to the sub along with the discrete LFE channel information. This allegedly lets the main speakers work more efficiently (their woofers aren't tasked with trying to produce frequencies from 30Hz to ~3000Hz all at once), but more importantly, lets the more capable sub produce the really low freqs that it specializes in. I'd also move the bass crossover freq from the default 80Hz to 100Hz or even 110Hz. This will even further help the mains' woofers.
There are articles online that can more explicitly describe just how low 6-1/2" woofers can reliably perform with sustained input (Audioholics is one of several good sites),... I'm summarizing mercilessly.
Immediate effect that you might notice for action movie scenes is a more compelling bass response than before.
You mentioned the Center channel just can't compete with the Left and Right channels. I agree with Zilch, use YPAO to set levels, then check with the test tone or some test tones and sweep tones downloaded from audiocheck.net. I would do this AFTER setting the speaker sizes as I mentioned. See what YPAO comes up with; if it resets them to "large," I put them back to "small."

Go to SVS/Hsu Research/some other subwoofer maker, to not pass GO, do not collect $200. With the recommendation I made above, you need as hefty a subwoofer as your pocketbook and anyone living with you will permit. Some try to compensate with two lower-grade subwoofers
, and though I've read that it helps with evening out the performance of the lower freqs, two smaller subs do not equal
the performance of a single larger sub.
