ya man, i went to my local audio places (best buy and audio express) and they could not fit any slim subs they had in my car, rockford fosgate 10" or 12". thats why im looking at powered subs right now, i know that i shouldn't sacrifice sound quality for a budget but im not, im just not willing to sacrafice rear seats ya digg? i would put this in front of my middle back seat which is a space about 15" by 10" by 12"
