I have a 2002 Maxima that already has a BOSE system in it. I want top add a sub in the trunk to get some more bass. Will i need to replace the bose system or just keep that and buy a subwoofer?....wat type of amp should i get and sub woofer. i basically wanna hook my audio system up but dont kno if i should mess with the already nice system it came with....its factory though...

thanks for ur help in advance
