Yaris T Sport 6 Speakers

[ilsondanni]

My Mum has recently bought a 3 door 55 plate Yaris T-Sport and is very pleased !

Since buying it, I have changed the stereo and that is as far as I have got.

New Stereo: Sony DSX-S100

The next step is that she wants some Speakers in the back...

I know that currently all 4 of the speaker channels are used for the "dash" and "door" Speakers in the front.

If I bought a "speaker adaptor" from Toyota (PZ417-B0240-60)

I am unsure if this would enable me to add 2 more Speakers in the back or not, as the Sony head unit only has 4 speaker outputs, not 6 ?

The only alternative I can think of would be to split the output of the head unit as shown:

HEADUNIT

----------->[FL]-->[CONNECT THIS OUTPUT TO BOTH THE LEFT DASH AND LEFT DOOR SPEAKERS]

----------->[FR]-->[CONNECT THIS OUTPUT TO BOTH THE RIGHT DASH AND RIGHT DOOR SPEAKERS]

----------->[RL]-->[CONNECT THIS TO THE NEW REAR LEFT SPEAKER]

----------->[RR]-->[CONNECT THIS TO THE NEW REAR RIGHT SPEAKER]

Any response would be great,

Cheers Dan.
