Would a mono block class X amp with a THD rating of 1.0% at 1 ohm be a problem for my subs. I have a pair of L5 and I want to know would this amp cause my subs harm with a THD rating like that?

The amp in question is the clifDesign CDX 10A.

Well i dont know if it would hurt anything but man thats a high rating, would think it would have an awful sound quality to it if anything.

Anyone else here have any information to share on the THD being 1.0% on a sub amp?

Don't think it would cause harm, but not recommended for SQ, but might work for SPL.

Most Class D amps run high % THD when in 2 ohms. This is common and should not be a problem even for SQ.

I kind of figured that it wouldn't be that big of a deal because its a sub amp anyway, but I just wanted to make sure. Usually I see sub amps with a .5% THD but never with a 1%THD though.

Thanks guys for the clear up on this
