I purchased two sets of Polk speakers, DB6500 seperates and DB650 coaxials. My question: are these speakers reliable as far as sound imaging. I will be running 2 ID Max 10" with a HiFonics BX1500BD @1ohm and using a HiFonics ZX6400 to run the Polks. Does this sound like a good set up because I want both quality movie and music sounds because I also have a 7" LCD mounted on my dash with a Power Acoustik PADVD-740R. Thanks for all your input!
