from all the opinions ive gotten the hifonics will do about 80% of the rms rating. i have one and i am very happy with it. but you might want to get a 1200 or 1500 so your sure your giving those type r's enough power. as for the type r's i have read people are satisfied with them but you can probably get better for the money. if you want to know more about them i suggest you go to the subwoofer forum and talk to Rovin he has them.
