Just bought Polk Audio RTi4 because I wanted some real speakers for my computer and it was on sale at frys.
here are the specs:

Electrical
Total Frequency Response	50Hz-27kHz
Upper -3dB Limit	26kHz
Lower -3dB Limit	60Hz
Nominal Impedance	8 ohm
Efficiency	89 dB
Recommended Amplifier Power	20-125 watts per channel
Inputs	Dual (bi-amp) gold plated 5-way binding posts

 
Please recommend me an amp.  Max budget $150, cheaper the better but I want it to be reliable.  I was looking at alot of t-amps but I am very hesitant to use them.  alot of them are like 15-25 watt per channel at 4 ohms or something like that? so would that be half the power at 8 ohms? I don't want to under power my speakers and fry them.  Please let me know, I am very noob
 
EDIT I bought a used Pioneer A-35R

what type of music do you listen to? 
 
I personally use a sure electronics 4x 100w Tripath for my RTI4's its not exactly the most bass heavy amp out there but its quite small and if you wish to bi-amp it is possible to do quite easily. The amp is about 60 bucks at parts express though if your desk happens to be metal its just an open PCB board so you'll need to build a proper case or it will short. There are better tripath amps out there for under 150 though. IMO 41Hz audio makes good stuff at pretty decent prices.
 
if you don't care about size and are okay to deal with craigslist or eBay there are loads of vintage amps with surprising sonic quality out there which will have a warmer more laid back sound. i say this because with the tripath, the RTI's can become very fatiguing giving you a headache if not EQ'd correctly.
 
happy hunting
