i have steering wheel controls, this is the only reason why i am debating this. Its a 1st gen. Im debating between ripping the sub out of my s10 because im giving it to my dad as a work truck and he dosen't want it. I have no idea if you can even hook a sub up to a stock stereo though. If i go aftermarket, i will be so bummed to lose the steering wheel controls, unless there is a way to hook them up. If there is tell me because i definetly will go aftermarket.
