Speaker Wiring for 2014 XLE base stereo

jproell2 · Aug 11, 2014

I bought the Rav4 with nav back in March and have been pretty disappointed in the low end response of the base stereo. I grew up with Kicker solobaric subs and was used to larger ported boxes. I want more bass, but no longer want to use up all the space in the back because of the kids stuff that has to be brought along anytime I go somewhere. I bought a small powered sub that could fit under the front seat. I know it won't compare to what I used to have, but just wanted something extra.

My question is.....Where can I get the wiring information so that I can get a high level speaker input for the unit. I have looked all over and can't find any information that I am looking for. I don't want to pull a lot of panels off the dash if I don't have to. I know I can find a grommet in the firewall to get the power wire through. I just need to get the speaker inputs so I can see how this will work.

Thanks in advance for your input.

You are going to have to pull out the head unit. Which is a simple job.

Thank you for that. Guess I am going to start searching the forums for advice on taking the head unit out.

Hello
No factory headunits have usually 12 v output , blue wire , which is used as switching power for AMPS or SUBS , .
According to schema in c7aea answer (thanks for it ) , in factory headunit this output is not available.
What is possible to use as switching signal for AMPS in RAV 4.4 ?
It is possible to splice some wires to E47 , A3 ignition 12V input ?

There is a 12volt switched wire for the factory head unit. I used it when I installed my amp.

In the diagram it is labeled as the gray wire.

The blue wire would be a constant 12 volts.

It is best to always test to confirm though.

Thanks for the help! I got the powered sub in. Now its just sitting under the passenger seat as I am trying to find a decent way of mounting it. Guess the unit I bought is taller than I anticipated and its in contact with the rear seat heater underneath the seat.

I mounded mine to piece of aluminum mounted between the seat rails. The other end is resting on top of the air vent and held down by double sided tape.

Did you use jl audio clean sweep to keep factory radio?

jproell2 · Aug 30, 2014

I just added a small powered sub. I didn't change any other components, so I didn't use the clean sweep.
