How much power do I need for my subwoofers?

That depends on what sort of bass impact you hope to achieve. If you just want to hear a bit more bass than your regular stereo speakers can put out, you can get what you need with an efficient 6-1/2" subwoofer driven by as little as 30 watts RMS. But when you're looking for really big bass, you'll need at least a 10" or 12" subwoofer and a minimum of 150 to 200 watts to drive it. Low bass notes are power hungry, and the more wattage you feed them, the better they sound. In general, the larger your subwoofer and the harder you want it to hit, the more power you'll need.

Remember, if you're driving one sub, you can "bridge" a 2-channel amp to get a significant increase in output. Our individual product descriptions list bridged output for each of our amplifiers. You also may want to take a look at our selection of Mono Subwoofer Amps, since their features and design are specifically tailored for the job of driving low frequencies.

We usually recommend that you drive your speakers/subwoofers with at least 70% (70-100%) of their maximum RMS (not peak) rating to get them to perform at their optimum. The closer to 100% you power them, the harder they hit and the better they sound.
