Why Doesn't my sub work with my headunit
I've recently wired a sub to my car and couldn't get the sub to work the wiring is all good but there is no sound to the sub the amp light is on the settings on my head unit for the sub are all good but still no sound, we tried my brother in laws head unit in my car and the sub worked fine then we tried my head unit in hes car and again no sound in hes sub, we sent the head unit back to pioneer thinking the rca ports were no good got a replacement one and still nothing will i have to get another head unit?
