I cant find the RMS rating for my subs, they are Absolute Audio VI1200 im assuming from the name that theyre 1200 W max but what about the RMS? Ive searched all over, even the Absolute site, it gives me nothing on the RMS rating. anyone know where I might be able to find the rating? Thanks in advance for any info.

I found that these subs are 1200 W max, I have the Absolute Audio PROD1800 Class D mono channel amp powering these subs, I cant find the RMS rating for this amp either, it has 3 25 amp fuses so im thinking this amp is putting out about 800 W RMS, now being that its a mono channel do the subs see 800W RMS each if that? Thanks in advance for any help.

Nope, each sub shares a portion of the total output power of the amp. I would put the output power closer to the 600 watt mark, so each sub seeing 300w.
