This is a reply I got when I told them the actual rms rating
On their qca3500d amp


Did you connected this ? we have sold hundreds of this listings with no issues whatsoever this is a perfect matched system. Just try it I am sure you will like it. despite of the fuses the amp specs are accurate. Thanks

lol. good ol 3rd world customer service.

I know right. I asked if I hooked up my system and it blew what are they going to doto reimburse me. Cause I'm not
Paying 50$ for shipping again. No reply yet.

I've always heard good things from audiosavings the owner is actually a member of CA.com and gives us discounts... Huh weird.

what did the amp rate when you clamped it?

It has 2X 30 amp fuses. From what I hear on here. 100 for every 10 amps.
600 rms. Great deals from this place. But shitty customer service.
I honestly don't know what clamping it means.

Just means they used a Clamp Meter or a DMM with a Clamp on it to clamp the power the amplifier sees at curtain voltage etc. Basically to find the ACTUAL rating of an amplifier.

Can you post a link to an image?

So pretty much a multimeter? Or do I need a specific clamp?

A clamp is a clamp lol so yes you need a clamp.
