I have a JL 300/4 and thinking about powering my stock bose speaker with it. I really dont wanna tear open the door and mess with the wiring so thinking about just tapping into the bose harness. I have the audiocontrol lc7i processor. I have subwoofer hooked up already. Just wish the speaker be a bit louder too. Dont need nothing loud and crazy. Will it work?

I have a friend with a lexus GS350 and he did the same on his car with the bose system and it sounds pretty good. Way better than mines, lol. I'm wondering if anyone out there did the same?
