from any testing I have done they have never performed how they should, either they are overrated or eveything else i ahve used was extremely underrated.
I've got a nice Cadence amp for sale that will do 750w @ 2 ohms, asking $250 though //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif
Otherwise I'd try and find an Orion 1200d or Viper d1200 for that price.... better chance of finding the Viper for $200 though //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
