I have installed an aftermarket soundsystem, ani was wondering if there are aftermarket headunits that would be compatable with all the controls that have subwoofer controls?

I think you are looking for compatability with the steering wheel controls. There are aftermarket companies that do this.
Here's one: http://www.autotoys.com/x/catalog/UNIVERSAL_STEERING_WHEEL_CONTROL_BY_PAC_SWIX_p_597.html

I have no idea who they are, but it shows what's out there. I'd go to a good shop and have them do it if you have no experience with this.
