Hey, I have an alpine MRV-M500 amp and an alpine speaker that is 2+2 ohms. Was testing the speaker yesterday since it was playing very bad sound. Not much bass, lots of cackling. Hooking up a reader shows 0 ohms on the terminals. What would be a good (preferably cheaper) good sounding speaker to pair with the amp? Or would there be an easy fix for speaker?

Have the amp wired with speaker wire from rear b columns in vw jetta 2012 tdi.

Would anyone have or know the colors for rear speakers wires in the lower b pillar, left and right side? Can't find a diagram online
