Apparently my car had a pretty serious subwoofer system in it prior to me purchasing. This did not come with the car. However, I see in the right side, trunk panel there is additional wiring...not cheap stuff either. I think 0 guage. How do I know if there is still something off the L7 amp to feed the subs. Is there a tell tale sign? What should I look for? I'm looking to possibly upgrade with a single 12" or something. Just to get a little harder hit.

I forget the name of the company, but they have a "kit" which replaces all of our factory speakers....all plug & play. Has anyone used them? Thoughts?
