Rear door speaker replacement?
 
I need to replace my rear speakers for my stock audio system.

Does anyone have experience with replacing the original 9.5 ohm speakers with 4 ohm speakers? Will the oem radio handle the difference? Will the volume with the 4 ohm speakers be diminished?

Back when I used to be an electronics installer we put new speakers in place of OEM, keeping the OEM head unit all the time. Generally it was a significant improvement in volume and sound quality. Over the 5 years I did automotive electronics installs I never had a customer bring their vehicle back because the radio was damaged by an aftermarket speaker.

A 4 ohm speaker will draw more power from the radio's amplifier, so the volume will not be diminished. If anything it will likely be louder, but like most things it's not that simple. Speaker design, power handling, speaker enclosure, etc. all will have an effect.

If you haven't already selected new speakers my $0.02 would be to select an entry level speaker from a reputable seller. An entry level speaker will have lower power requirements vs a higher end set which would likely be underwhelming unless you add an aftermarket amplifier to supply them with adequate power.

Perfect, this is the exactly the type of real-world based advice I needed. Thanks! :icon_beerchug:
