I have a 2005 Chrysler 300 Limited. I have the stock Boston system with the amp and I do have the three speakers up front. No navigation but I do have the steering wheel controls. I just bought a Pioneer SPH-DA210 dd. My car is only a single din or din and half. Either way not a double. So what all will I need to make this work as far as the kit to turn it into a double and all the wiring harnesses and what not. If anyone knows the models numbers that would be awesome. Second, pretty sure my factory amp is blown since only my front speakers work. But I am buying the Kicker replacement stock amp next month and then will be adding subs. Just want to make sure that problem will not interfere with me installing my new radio now.
