Here we go...Iv wired my ground and battery cable perfectly. The only thing is it wont power on. So i went to a near by audio place and they said that they will finish the job for like 1bill. So i decided to complete all the things that the shop complained about fixing(thingd i was already gonna do). So i did it. Now i need to know how to install my stupid converter thing. It alows me to install my amp to the stock head unit. but i dont no how to take my deck out. Do i need to?? Help
