For this purpose, you can check your speaker’s power range as it may be specific in watts like; as you need to power speakers rated up to 1000 watts, then your speakers must have a recommended power range of 1000 watts. But don’t try to drive your speakers with 1000 watt if they have less power range to handle, like 800 or 500 watt, which cause damage. So Team Wooster audio expert advice is to check your loudspeaker speakers specification, specially wattage handling, with the nitty-gritty and then purchase an amplifier for it.
