Audio equipment ratings - any suggestions?

Are there any websites that specialize in rating audio equipment? I have read almost every stereo post in the last two years to decide which amps to get, and I still can't decide.
I am running:
-4 dB651's inside the boat
-1 10" sub (Wetsounds)(plan to add a bow sub in a box later, so I would like a decent 2 channel class d amp for this)
-2 Pro80's on the tower
-Alpine 9881 head unit

I have a Crossfire VR404 amp I might keep for the 4 polks. So I need a sub amp and a amp for the tower.
I am trying to keep the cost down as much as possible, since the rest of the equipment already broke the bank. I don't need the best.

Any suggestions for amps or places to get quality info about amps?

Thanks for the help.
