nissan subs

I have a nissan armada with bose speakers in it and id i get subs in it if i would have to change the bose speakers out??
if anyone knows or if i should or not please post.
thank you

no you dont have to change your bose speakers out. if you are going to use your factory radio you will have to get an adapter from speaker level input to rca output so you can hook up an amp to run your subs. if you go to best buy or a car stereo shop they can show you what you need.
