Optimize your sound with a switchable low-cut filter

Rock sold down to 2 ohms!!!

I would like to start of by saying that this amp sounds amazing and powerful! Im running these things on an old pair of jbl srx 4733x im running them down at 2 ohms and these do there job easily. i normally only run Qsc on tops because of how tight the sound is. if your wondering why i dont run them on subs is because of low dapning factor but besides this it sounds amazing paired up with a crown xli 3500 my church has running the subs!
