I have a HP pavillion i bought less than a year ago, i want better sound quality i was wondering if these speakers would work on it: http://www.radioshack.com/product/index.jsp?parentPage=search&pg=1&summary=summary&cp=&productId=2763905&accessories=accessories&kw=computer+speaker&techSpecs=techSpecs¤tTab=features&custRatings=custRatings&sr=1&features=features&origkw=computer+speaker&support=support&tab=summary the problem is my laptop only has two headphone jacks, and i dont know if they will put out enough power for the new speakers? is there really no difference between a headphone jack and a speaker jack? would their sound quality be the same as if i was hooking them up to a PC
