need cheep amp 20hz 60hz ideas?

Hey all, So I need an amp to drive a seat shaker that wants between 28-55 Hz @300rms. I can't seem to find any modern (read cheap) amps that DON'T have a cut-off.... does anyone have any ideas? -thanks PS its to drive some of these: http://www.simkits.com/product.php?prodid=556 Ill probably be installing at least 2 of these units maybe up to 4, however I have infinite space as this is going into a building, so if I need a few monoblocks that's fine, if I can get a 2/4 channel unit that's great too. I would prefer 12V as all my control relays are wired for 12V but If I have to go to 110 its doable...

that thing looks EXACTLY like a 25 watt Aura bass shaker with someone elses label stuck on it.. they dont say 300 watts continuos. i personally wouldnt even consider it. but its your money. SO... a JL 500/1 amp can dial in almost perfectly the frequency limitations you mentioned. it seems strange to me that no information (other than the manufacturers)about them exsists, yet you can find all kinds of people having fun with real bass shakers and other brands (partsexpress.com sells a few) all over the place. wouldnt you think there would be at least one customer posting a youtube video about the simkits body shaker? be cautious.have fun.yuk
