Not sure about the model, but i had a 12 exactly like that and i gave it 1200w daily for about a month, then sold it, and its still going strong. I pounded the **** out of it.
I had one of these subs briefly a few years ago. rated for 400rms and 800 peak if memory serves me right. i had 400 watts on it for about 5 minutes before it started to stink BAD. I boxed it back up and took it right back to the store and got my money back. I bought it at walmart if that tells you anything
