I currently have an 87 Buick Grand National and am trying to replace the speakers. The car has a 6 speaker system and the front 4 speakers are wired in parallel (2speakers per channel). The original ohms across each of these parallel channels is 2.85 ohms (1/(1/4+1/10)). The HU has been upgraded to a Pioneer DEH-P76DH unit running 4x22Wrms.
I want to replace the speakers with 4ohms speakers all around, but doing this to the parallel wired speakers will drop the ohms seen by the HU to 2ohms (down from 2.85 ohms). Would this cause issues for my headunit?? Overall the HU would see 2ch x 2ohms (front parallel) and 2ch x 4ohms (rear)
Thanks for the help!
