Hey everyone! So i just bought a 2013 edge limited and i was wanting to replace the stock sub with the JL stealth box. I was wondering what amp did you use for it or do you have to replace the stock amp to get good bass out of the system? I herd that SYNC has the safety feature when you turn the volume up the bass automatically goes down will i be just wasting my money or will the new sub make a difference? Any help would be much appreciated!
