Hi everyone. I haven't done much with car audio for a while now due to the birth of my son. I didn't have trunk space before, but now I finally do. I want to put something back in my car but I don't have a lot of money to spend. I would prefer an SQ system, but thats not set in stone. For the time being to cut down the cost, I am keeping my stock head unit. I have an old Kicker L7 which I am willing to use but would love something else. My car already had an upgraded stereo when I bought it, but just as the sub, would love something new. My car is Pontiac G6. Any and all suggestions would be awesome. Thanks everyone.
