Easy guys,

Trying to figure out what amps I need to power 4 W8C's.

(New to this so would appreciate someone checking my work)

So...

The low-mid driver is rated at 300W @ 8 ohms.

Two will need 600W power.

As I will be running two per channel, I will need an amp that can do 1200W (2x headroom for optimal power) @ 4 ohms per channel.

Will the QSC Powerlight 4.0 be okay for this?

The high-mid driver is rated at 150W @ 16 ohms.

Two will need 300W power.

As I will be running two per channel, I will need an amp that can do 600W (2x headroom for optimal power) @ 8 ohms per channel.

Will the QSC Powerlight 3.4 be okay for this?

The HF driver is rated at 60W @ 16 ohms.

Two will need 120W power.

As I will be running two per channel, I will need an amp that can do 240W (2x headroom for optimal power) @ 8 ohms per channel.

Will the QSC Powerlight 2.0 be okay for this?

I would really appreciate someone checking all my calculations and giving me some reassurance.

Based on my calculations, all of this is correct and the QSC Powerlight amps I have listed will be powerful enough for the job.

Cheers,

Avantí Star
