A:AnswerI had to wait to schedule the installation because a part needed to install the radio in my car had to be ordered, but the install took about 1 hour and the radio looks great in my car and sounds great as well.
A:Answeryou might want to consider upgrading or adding an amplifier. a friend had the same problem and he had to change his amplifier to match the new speakers he installed (it was a question of matching wattage) it produced a fuller, richer and more clear sound but also helped with power drain.
