i run the scosche kit, as i could more easily modify it to mount the pouch on the top, alternatively can also run 2 1-din units, where the metra kit is a fixed 1-din only kit

either can't hurt to try, definitely cheap enough-- if there were someone near chicago with a '22, i'd have no problem pulling my kit to test fit some weekend. if nothing else, for the future knowledge

they do get software updates to be compatible with newer vehicles, and also to update the connection/wiring diagrams. i know about it, but never used the maestro for it.

Whether it is driven by power amps in the head unit or line level signals, I don't have a clue. Same with my previous 2017 BRZ which had 6 speakers and an amp in the trunk area. I assume that the 2022 is set up in a similar fashion. Does the head unit have a power amp capable of driving speakers on its own? Are all 6 speakers in the BRZ connected to the external amp in the trunk area?
very different from your ascent. but typical for toyota. a number of other models are wired very similar. my tacoma is, just without the amp.

from the info i've collected so far, i've gathered that there's 2 sound systems offered now. the limited brz has a 8-speaker system, with amp, and the premium brz has a 6 speaker system, without amp. the major difference from 1st gen is the premium dropping a pair of speakers, and the amp--i believe. the 6-speaker part is confirmed, the non-included amp was anecdotal from 1 thread from a new member connecting a sub...


the front channels run into the tweeters on the top of the dash. there's a 4-wire plug on the tweeter with internal jumper pairs inside the tweeter to connect the 2 pairs of wires. 1 jumper for + input to +output, and 1 for - input to - output. disconnecting the tweeters will kill all the front speakers.

from that tweeter connector, the full range signal splits to the amp in the trunk, and the dash midranges(if equipped, premium won't have them, unclear if the wiring exists though).

once the signal hits the amp, the amp has some specialty low-pass filtering, and sends the the amplified result to the door speakers only, making them operate like subwoofers(but they're only low-grade 6.5" 2 ohm speakers, so they do a terrible job at it). there's a thread by frs2gt86 that goes much more into depth on the specific frequencies that the amp covers if one is so inclined, but i feel it's starting to get off into the weeds in this conversation.

for the 1st-gen, the dash midrange and tweeters both have built-in high-pass filtering, the diagrams i've seen of the 2nd-gen indicates zero changes. the same diagrams have also indicated that the amp/door speaker operation appears to be unchanged as well.



the rear speakers are directly connected to the rear speaker output of the head unit. there is no physical filtering on the rear speakers, though some speculation that the oem head unit limits frequencies going to those speakers. but no one's really ever cared enough to dig into it past that speculation--anyone that cared enough for how it sounds just replaced the head unit and speakers.
