hi i am thinking about upgrading my rti8 to the lsi 15 but they are rated 4 ohms and i am not sure that my av will push them. i swear i read some where that it would but i just can't find the post. i know the the sc 05 is only good for 8-6 ohms but i remember in the post they said it has enough power. i am right or was i imagining this?
