Don't get lost in the numbers. I've been matching speakers and amps for over two decades, and I'm here to tell you what speaker wattage you truly need.

You'll see "100W" on a speaker box, "200W per channel" on an amp, and then someone says "peak power" or "RMS." Your head starts to spin, and next thing you know, you're staring at a spreadsheet trying to figure out ohms and decibels. I’ve been knee-deep in this stuff for over twenty years, testing gear, blowing a fuse or two (metaphorically, mostly), and helping blokes just like you sort out their setups. Whether you're trying to get a decent sound in your living room, kitting out a small pub, or just upgrading your car stereo, understanding wattage is key. But it's not about going for the biggest number you can find. Far from it. Honestly, most of what you hear about wattage is a load of old cobblers.
