running bazooka ba 460 off pioneer 3900 currently to polk 6.5 up front and pioneer rear door. I have a 600 watt amp with a sub so bass is not the question. I want to upgrade the fronts to components, and put the polks in the rear doors, the best i can find in my price range are infinity reference 60?? 6.5 but they run at 2 ohm. the amp is 60x4 4ohm. Do i have to get a 4 ohm component system or will the amp convert to 2ohm when hooked up to 2 ohm speakers.
I appreciate your help. Please excuse my ignorance regarding car audio.
