Front door component crossover and tweeter install help.

My Audio Control components had 2 crossovers for each side (hi pass and low pass) for a total of 4 crossovers. I ended up putting mine under the seat with the tweeter level switches pointing out for quick adjustments if needed. I ended up putting a few grommets in the carpet (passenger side shown) which will one day be mounts for the DSP. The countersink fasteners nestle nicely into the grommets and I use a rubber washer (circled in red) to isolate the APS plate from any buzzing. The ABS plate was drilled and tapped for very short 1/4-20 fasteners.

 

The grommets are a really nice touch.

I take it you don't have any fears about the HVAC ducting blowing directly into them? I had planned to do more of a tac0tunes mounting plate off the seat bolts that raised the amps just above those duct pieces to avoid thermal cycling of my electronics.

 

Well, as it sits now, it's not ideal...but I do intend to add taller screws and stand them off the carpet a bit as I did yesterday for the amp plate. The amp plate sits about 3/8" above the carpet...but the nap of the carpet makes it look like 1/4". It's just high enough to align the air gap with the outlets of the HVAC ducts. In the end, it will not be perfect but allow enough air to get through to be an adequate solution.

 

The spacers I used for the amp plate were these 1/4" nylon spacers (from Lowes Hardware) with a few rubber washers to get me to 3/8". Just discovered that rubber faucet bibs work better and may end up replacing this tomorrow when the amp goes on. Then will modify the crossover plate to allow more HVAC 'flowage'.

 

lol, done that way too many times, just started walking through all the different departments trying to locate hardware that works 'just right'!

it's cool you found something!

 

Bet it looks a whole lot better.

Wait. It does. Mine are encased inside the runbber

 

Adding an amp was smart. A sub is smarter

 

And for the record my crossovers are zip ties inside the door. That is dumb. The are also set slightly differently which is dumber. I think

 

I’m sure that it does look way better, but the juice wasn’t worth the squeeze cuz I’m not looking at the wires when I get in or out, and they’re outta sight when the doors are closed.

 

It was worth it. Maybe 3rd gens are harder.

 

Oh I added to it all right. One amp for the door speakers I mentioned, another for the 12" subs behind the seat.

 

whew.i was worried.

 

Yeah, I dunno. It was definitely tight in there. Part of my worry was also the possibility of damaging the wires already inside the rubber.

 

Hmmm trying to envision this...I had a 2nd gen and love the "everything is in the door"
And now I have a 3rd gen I am going to install components in...
I'm trying to understand how the speaker wiring runs...
+/- out of radio to the Dash tweeter that has a built in HPF I'm guessing? and then the 4 pin connector which is 1,2 +/- from the radio...3/4 +/- continuing on to the door speaker, jumpered in the connector?
I found this picture in the review of the harness for the Front dash tweeters on a 3rd gen tacoma..
It's

$14 METRA 72-8110 METRA - Subaru/Toyota 2008-Up - Speaker Harness (72-8110)

METRA 72-8110


Going off my artistic labels...
I'm guessing 1 and 3 or 2 and 4 are the feeds from the radio. I would need to identify which is which for this...
Let's assume 2 and 4 are the inputs from the radio. They are then Split, sent out 2C and 4D to the tweeter and then A1 and B3 carry on to the door woofer.
So if I were to Cut all wires A, B, C, D.
Cap off C2 and D4
Connect speaker wire to -A2 and +B4 and run those to my IN on my crossover (again assuming that A2 and B4 are the hot signal from the radio. Reverse this if it's A1 and B3)

Now the Tweeter out +/- of my crossover runs back up to previously Cut C/D wire. Connect that +/-...Terminates at a tweeter.
The Woofer out of the crossover wires back up to here and connect to -1 and +3 to send it back through the factory wiring to terminate at the door speakers...

Making sure that in the white side factory connector there is nothing jumpered...all the jumping happens on the connector side or on the factory installed tweeter?
This at least lets me put the crossovers maybe in the kick panels...and fish a few strands of speaker wire...

 

you've got the right idea-- i attached an image from tac-o-tun-e-s harness that specifies the pins to confirm what you've got so far.

i can't make out which side the 'side-tab' is in your picture, i would verify that against the attached picture-- i've run into a number of vendors that use black for positive, and white for negative, though i normally expect black is negative and white is positive.

i'll do you one simpler

here's a diagram with my expert ms paint skills

 

And then turn around & Toyota is using some kind of wild violet and green. Thankfully, I have the 2023 entune 8 inch which finally separated the speakers out into a separate connector. Now I just have to find 12 V accessory, ignition power and the ground on the original harness for this model radio which no one has Mapped as far as I can tell. Plenty of wiring diagrams for the ones before they separated the speakers out into their own connection.


Oh and we are art masters. Picasso is a wannabe

 

Ditch the passive crossovers and run them active from a DSP

 

definitely has it's advantages.

in this case, would be a lot harder trying to maintain the oem wiring.

 

Poking around here...the 2023 non jbl easily jumps the speaker outs with the red wolf harness...which is also incorporated into THIS harness. I was thinking I could disassemble this, ID the wires/speakers and then find an Acc 12v and ground to splice into on the other harness. Does anyone know which harness this connects to and what the pin out map is for it?
I'm buying it if not and I'll figure it out and do a write up.
I've seen it disassembled to show it's mono jumperd to one channel only which works fine for a mono amp...
And the red wire is the normal "blue" signal on control wire.

Just posting...The non-speaker harness connects to the grey harness right next to the black speaker harness.
It looks like they intentionally wired everything just because it's easier than wiring the few connections that are actually used.
So now I search for the pin out on that gray connector adjacent to the speaker output. I believe I read somewhere that the blue is a ground in the corner… I'll have to figure out where I got that from.
