Can anyone confirm whether my system has an amplifier hidden somewhere in the car?? It's a North American model, with the most basic stereo system (head unit says "Professional"). Crappy subs mounted under the front seats, and you barely know they're running. I can't imagine there's an amp pushing power to these things.
I thought you had to get at least the Hi-Fi system to get the subs under the seats? Other wise what is the Hi-Fi upgrade, just the tweeters in the side pillars?
