How many watts do I need for my receiver?
Most recommend between 25 and 400 watts — some even more. Try and pick a receiver that can deliver a constant amount of power within the recommended rating, so if a speaker requires between 25-150 watts, a receiver that can put out 45-100 would suit you very well.
What amp do I need for 300 watt speakers?
Sample Amplifier Power Rating Chart:

| 1 | 100 watts | 30-100 watts |
| 2 | 100 watts | 60-200 watts |
| 3 | 100 watts | 90-300 watts |
| 4 | 100 watts | 120-400 watts |
How do I know what size amp I need for my speakers?
Generally you should pick an amplifier that can deliver power equal to twice the speaker’s program/continuous power rating. This means that a speaker with a “nominal impedance” of 8 ohms and a program rating of 350 watts will require an amplifier that can produce 700 watts into an 8 ohm load.

| Room size in square feet | Wattage sum (peak) |
|---|---|
| 1000-2000 | 2000 watts |
| Over 2000 | 4000 watts |
How much watt speaker is good for room?
A receiver with 50 watts per channel should be adequate for small to medium-sized rooms or speakers above 90 decibels sensitivity. If you have a large room or speakers below 87 decibels sensitivity, try and get 100 watts or more.
Is 100 watts per channel enough?
One hundred watts per channel might not be enough, or 200 might be better, but an honest-to-God 300 watts might be what it takes to rock your world. Even if it’s just the occasional party where you really want to blast the system, you need to buy enough power.
