Right!! My current sony HU had audio front and rear + audio bus what ever that is? So all 4 speakers worked fine but i just changed my HU tonight this one only has 2 ports for front speakers and audio bus cause i have them through an amp all i get from rear speakers is a buzzing noise how do i do it so all 4 speakers will work? Sorry if it sounds confusing

How many channels is your amp ? If it's two run the two better speakers from that. Plug the other speakers into the HU.
If it's four no probs, wire all four speakers up.

What speakers are you amping up ?? (details, rms etc)
