A Heyand only then will they hit hard. As far as getting more info on them you would want to check on the Internet; type in "Orion HCCA" into a search engine and you will find all the information you want regarding these subs. You should also be able to find out if there is a local dealer near you. Just remember: to make any system bang, you have to build the right speaker box for the right speaker, and hook it up to the right amount of power in order to have any system work to its full potential. Thanks for writing.
