 Pioneer Avic D3X replacing Mach 460
Ok guys and girls, I have a 2003 GT and I just purchased a Pioneer Avic D3x HU w/ navigation, ipod, bluetooth, dvd, the whole nine yards. From what I've read, replacing the components of the Mach system is a real pain in the a--. I am also considering replacing the speakers as well if this will make installation easier and improve the sound system as a whole. Can the new HU and new speakers be installed and hooked up with the Mach amps? If so what do I need to do this? What installation harnesses and connectors do I need to install the HU? What is recommended for speakers? Do you recommend a component set to replace the door woofers and door speakers respectively? Will I need bass blockers? I have done a lot of searching but I've heard mixed approaches to this which is why I'm making another post. Thanks for your help! |
