firebirddude98

i have a pioneer cd player im wanting to put in my 98 firebird. the bird has power antenna and a steering wheel control. the original is the monsoon version and has front, middle, and trunk speakers. the new stereo has wiring to front and mid speakers, and doesnt hook to the antenna and steering wheel. gonna hook a 4channel amp to the two back speakers (putting in some big 6x9s and 2-12" subs) wondering if there is anything i could do to hook into the steering wheel and antenna with the pioneer player i have. thanks for any input friends
