Audio system similarities between Tacoma and Subaru Ascent

I have both vehicles and am curious about what is interchangeable/similar between the two. I purchased the Ascent after my Tacoma, when talking with the dealership the salesman told me how the two companies interacted occasionally.
I can't quite get anything from search engine queries, but there's got to be more in common between the two than the door-lock indicator/noise. Both have 6x9's up front and 6.5's in the back (only so many options of course).
I'm just asking about the non-upgraded stereo systems on the two models. I'm hoping for a "Yes, the Tacoma and Ascent stock speakers are the same and are made in _______". Because I think that would be neat.

 

Thats funny. Did you realize that salesmen have a very visable way of telling when they are, lets just say, telling you a story? Its when sounds are coming out of moving lips

 

Toyota owns 20% of Subaru per google search. Not sure they use same suppliers. They do share 2 cars cross platforms.

 

I saw one that said Toyota owned a "small" share; a fifth is not small. Thanks, I'd assume they'd help cut costs where they could by using same supplier. Not necessarily speakers, but I think we're on to something here...

 

Truth, I did notice that the man could not identify half of what was underneath the Ascent's rear mat area. Like the symbols on each separate little panel under the board (scissor jack, jumpers, tow bolt). He learned more from me about them then I did him... I just looked it up right there and shared.

 

No idea about the ascent. But my brz used a very similar dash setup. Door speakers were separately amplified, poorly. Except it has a mid and tweeter on a 4-pin connection to the tweeter in the dash, where the Tacoma runs the same 4pin connector to the dash tweeter and then to the door woofer.

The radio power connections use the same plug for me as well.
