it def. wont be enough power! most home stereos with powered sub boxes only put out `100-200 rms and most of the time are capable to handle only an 8 or 4 ohm load nothing lower
and a good ht box designed up for it and it will get so **** loud! also your gona want some speakers that will be up to par to keep up with the bass //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gif
