Relation Between Ohms and Watts

[Aeridox]

Ok so i have been looking on Ebay for speakers and an amp and decided that i need to raise my budget.

I was looking and i would see that a set of speakers will run at 8 ohms at 500 watts.
Then i would look at an amp that says that it is 5000 watts but at 8 ohms stereo it only has 200 watts.I used a set at 350 watts per channel and they were barely loud enough. I am confused of the relation between watts and ohms. And could anyone recommend a wattage amount that would work for parties and medium crowds.(i may be way off base with this but i am getting a little desperate) I am trying to get a set that would be loud without breaking the bank.

Thanks in advance.

Welcome....
Do not buy a speaker by watts. Quality in build and sound is how to buy speakers. What you have to look a the efficiency. Also what some people consider loud is ear piercing distortion. A true 5000 watt amp is very difficult to make and for this reason there are not many of them around and they are quite expensive. As for your question look into a nice pair of Name brand 12 or 15 inch and horn speakers and a proper amplifier to drive them.

A professional grade, full range speaker system should spec out at no less than 100 dB sensitivity. The higher the sensitivity spec, the more SPL the system will produce. Be wary of "mystery meat" cabinets that boast impressive specs ~ most are inflated.

The ticket is to shop first for speaker systems that will fulfill your needs. Then purchase an amp to drive them. It's OK to go a bit overboard with amp power dissipation, that's where your headroom comes in to play. But I wouldn't suggest driving a 500 watt system with an amp that's capable of 1500 WRMS dissipation to the cabinet.

Hope it helps.
