New user here, and im just getting into home audio as well. Apart from my home system, I picked up a pair of Gemini gsm 3032s and and a QSC gx5 power amp. I did a bit of research and the speakers are 550w peak, and the amp is rated at 500w per channel at 8ohms, most reviews state its a great amp with lots of power. So it seems as though its a pretty well matched pair. The amp however, even maxed out, still doesnt seem to come close to what these speakers can handle. Ive just been using a laptop to the power amp via a mini stereo to RCA cord. I found a B and K pro5 pre amp for sale cheap locally, will this make a big difference, or should I start looking for a bigger power amp instead

Your amp - almost any amp - does not operate even near its peak power out 90+% of the time. Just start with the volume very low and turn it up slowly to your listening level, unless a recording tends to have very high and very low moments that alternate quickly. A good example of this is modern romantic music: Sibelius, Mahler, Bruckner. In that case, err on the quiet side to start with and then see how loud the dynamic peaks are and tune them to your taste. But a warning: make those loud parts too loud and Caucasian Blackplate told you what might well happen.
Observe, before you think. Think before you open your yap. Act on the basis of experience.
Its clear to me I came to the right place. I highly doubt that the headphone jack on my laptop would even be close to 1.2v so Im going to pick up the B&K pre amp and start there. I appreciate the replies.
On a side note, once it is built to my satisfaction the system will be used in a large outdoor living area, used to play all types of music at different levels. All aimed at pissing off my neighbors!
Do be careful with those speakers. Yes, they are super loud and are rated to take a lot of power, but try putting 100W into them at 30 Hz and you'll likely tear the woofers apart.
Your laptop probably won't put out more than .3V, so a preamp would help.
Welcome! damone.
when choosing a preamp or processor, remember, this is the heart of your system. Buy the best that you can afford.
Check the output level of your laptop. That amp needs 1.2V to be driven to full output, and its input impedance is > 20kΩ. It could be that your laptop audio out doesn't put out that much, or only does so into a low-impedance load.
If you can't find that out, try driving the amp from something that puts out a line-level signal, like a CD player or tuner through its RCA or XLR outputs. (Headphone output are always something of a crap shoot.)
Even though the manufacturer of your amp does not provide any meaningful power spec, they imply that the amp puts out 500W rms, though they call it "program" rather than "rms," and don't specify what distortion level that's at. To find out what it puts out, either write them, or get hold of one of their distributors, like Sweetwater. (It may be that "program" is actually rms - it's just hard to tell.)
Your speakers are spec'd to handle 275W rms. Remember that each doubling of power gives you 3dB additional SPL. So, if they are getting 100W or more, they should be within 3-4dB of their full output, which is pretty close.

so, I CAN'T help you on that one. But, hey, if you can DANCE to the music, good going for you![Edit: Found a pic of a B&K-Pro5. It is pretty nice looking and seems to go for $125.00. It would probably make a nice match and solve any level issues you may have.]
