Hi, i have a 97 gt vert. with the mach system, i would love to get more bass out of the car, soo i have been looking into some subs, i have and aftermarket HU, and was wondering what type should i use. i was kinda thinking of getting 1 to 2 kicker l7 10" would those work, or should i go and buy the mach 1000 system upgrade, and have the 10" subs that will fit without a problem in my trunk??
