hello, everyone! i posted a thread about hooking up a new radio before and i went to get a price on it. they said it would cost me between $250 - $350 to make the radio kit,$75 to hook up the steering wheel interface and extra for anything else. by the way, i have an 06 acura tl non-navi. i don't care about bluetooth getting hooked up or the center speaker working. i just want the door speakers, rear speakers, and weak subwoofer to work with the new radio. HELP!!!!!! i'm getting it done at earmark in addison, tx. thanks everyone. this website has really been a big help to me! sorry for the long story!
