How many Ohms are my dash speakers in 2017 SR5 non jbl? If they are 2ohms, can i put 4 ohm speakers

Can i put some 4ohm Kicker 3.5 speakers in to replace my factory dash speakers?

 

I’m not sure if factory is 2 ohms or 4 ohms (sorry), but if factory is 2 ohms, and you put in 4 ohms, you will probably notice a decrease in volume, since the amp will be providing less power to the speakers.

 

Just like @DarthMurdicide stated you will see a decrease in volume. It happened with me when I installed my 4 ohms fosgates. I hope to offset that when I install a 4 channel fosgate amp for more power

 

its my understanding - could be wrong though - the dash corner speakers are 6ohm speakers.

If you pull one and look at the backside you will see whats stamped there

 

^^^^^ Do this

 

You will be fine with 4 ohm speakers. The center speaker is a dual voice coil speaker. Each dash corner speaker is connected in parallel with one of the voice coils of the center speaker. The resulting impedance is very close to 4 ohms [actually a little less] for the left and right channels. 4 ohm speakers will work if you do not reconnect the center speaker. I disconnected my center speaker because it destroys a lot of stereo separation in addition to not allowing the proper impedance. The corner speakers are driven by the head unit so you don't want to go too low in ohms. Leaving the center connected will load the head unit more and may in time blow it. The center speaker just produces a fake center channel by combining the left and right speaker signals into one speaker cone. The Tundra dash is not wide enough to justify a center speaker. Maybe this is more info than you asked for but there are some here that don't understand the function or operation of the center dash speaker. Some like it, some don't.....I don't.

 

If the original speakers aren't blow you can also use a digital volt meter to check the impedance.

But I fully agree with the above and wouldn't worry about the center channel. Its not a real center channel. Its just a summed left and right.
