No there run off the receiver. And the receiver seems to actually put out more powerthan the spekers can handle at times. But they never distort or have a bad sound. It's hard to explain. Basically I got the cheapest receiver that can decode HD audio(new) and a set of speakers that match it well
just as in vat audio u want to match your amp and speakers correctly. (especialy if your on a budget). If I got a $2000 receiver it would be overkillfor my speakers and visa versa. Bottom line Tho. I love the setup gets very loud and very clear.
And yes I'm being a ****** about building my sub lol. I have no computer at the moment. So until I get it back I'm posting and viewing links that everyone posts on a iPhone. Which at times is a lil slow with no 3g or wifi.
Alotof ppl are posting links to 15sand 18s. I don't have the room for one of those which is why i would rather go with a very good 12"driver and a god plate amp instead of just a mediocre 15 and amp
