oh wow, that's wild but also pretty awesome in terms of swapping then.

That functionality must be built-in due to the JDM cars shipping with no head unit.

FYI, For anyone doing the rear amp/door replacement, As has been discussed, the "low" level into the amp, as has been discussed previously are actually just a split off signal from the front dash speakers. As such, I went ahead and added an Audiocontrol LC2i to do level conversion, then ran the bass output to my basshub sub amp and the full range to the door speakers amp...., much improved from the straight signal to the amps. Particularly the cleanliness of the bass.

I still feel the treble is harsh/staticy, leading me to believe I must've boogered something up in this whole process or the head unit had some kind of mfgr defect. But, I'm probably past the point of no return to claim warranty. So at some point, I'll be going the full dash replacement along with some rewiring. For now, I'm turning the EQ down on the mid/treb and it's bearable, but not clear.

Hopefully this gives the aftermarket some time to develop better integration for steering wheel control, rear camera, etc...

I would love some plug and play harnesses, brackets, etc... for those items by the time I'm ready to make the jump.

I'm waiting on a full replacement because the stock unit sucks. I've never been more annoyed with a head unit in my entire life.

Oh sweet relief! So in the end I bypassed the factory Amp, put in a 4 and 2 channel amp through an Audiocontrol Lc2, which gets its signal from the rear amp input, which is a weak high-level signal.

The 4 channel powers front doors and a pair of 6x9s in boxes in the trunk firing forward. Then the 2 channels powers the basshub in the wheelwell.

The issue was that, even with the midrange eq all the way down, there were treble frequencies that made it unbearable, like staticy-feedback. Awful, so bright it was unbearable. In the end. I added an EQ with 28 or so bands and FINALLY, It sounds okay. I had to really crank down the 5k-6.5k bands, that's where that piercing pain was coming from.

FYI, I Used an Expert PX-2 eq, control everything from my phone, it's really slick, and in the absence of any kind of real eq on the head unit, as good as can be expected imo.

Sounds like you nailed it! Well done.

The treble distortion in the Limited is absolutely horrendous! My quick-and-dirty solution was to just disconnect the gawd-awful el-cheapo Pioneer polymer tweeters in the dash.

OEM Audio+ speakers and pulling the treble and mids down has mine to where it's quite good imo. Although I could improve it further by using the 9 band EQ on my phone vs the the in-car 3 band. That 3 band EQ isn't the greatest (especially stock speakers) because there's harsh frequencies between the "mids" and "highs" as said.

Would love pics of your setup.

I haven't done anything like this install before, how much work was it?
