I have some audio equipment i bought in late july and i used it for about 2 weeks. i sold the car that i used them in and i never felt like hooking up the sub and amp into the a4 and i have some college expenses i have to take care off. It is a infinity kappa 12 inch 1200watt boxed along with a ultralinear 2400watt amp. i spent well over 500 on these two things but right now ill sell em for 220. ill also throw in a new 9 gauge wiring kit.
