I want to add a "I don't trust you with my stereo switch" as well as a switch to turn it on without the key present.

When I did mine, I had a couple issues to overcome. 1st, Mazda made the audio system very modular. You can add BT and Nav and Satellite to it in sections. Problem being, mine came with BT, and after I installed the new radio, the old BT module kept trying to pair to my phone. I eventually had to unplug it (above the glove box) because it wouldn't pair to the new radio while it was trying to pair to the old BT module.

When I had the illumination wire hooked up, I got noise through bluetooth (streaming) on my new radio when the car was running. I disconnected it for now, but when I go back in, I'm going to use a relay to see if the noise goes away.

Finally, when I did my steering wheel controls (I used a Maestro SW, but a Pac SWI-CP2 would be a good choice as well) I had to grab one of the wires at the steering wheel so my BT buttons would work. It goes from the steering wheel, through the BT module and since I disconnected the BT module, it couldn't see those buttons, or they are completely isolated from the radio. You can most likely get them at the BT module, but steering wheel was easy to get to.

Also, I picked up a new daily, and I'm considering moving up to 15" IB subs, or 12" enclosed subs, and might move my Acoustic Elegance 12's to the new daily. I haven't decided yet. It's a smaller car, so I don't know how much space I want to give up.

The IB wall wasn't super complicated. I made mine from 3 layers of 3/4" MDF, and recessed the subs 3/4". I mounted it with metal brackets I picked up at Home depot. I left about a 1/16-1/8" gap around it, and filled the gap with black silicone to (hopefully) avoid squeaking. So far so good.

Sorry you didn't get a listen at Finals considering how similar the cars are/will be.

I havent had issues with the bluetooth module or the ilumination noise.
As far as the steering wheel controls, the workshop manual mentions that the bose and non bose wiring is different. The Bose unit does have the phone buttons on the harness and the non bose doesnt.

Got the power wire in.

The OEM battery has a fused terminal which has and empty spot with a 60 A fuse that just so happens to be what the Zapco ADSP-Z8 needs.

So I got a ring terminal and crimped the wire, got a 10 mm nut to hold it in place and used wire loom to make it look oem.

261248


Used the OEM positive terminal cover and it looks like nothing happened.
In case I blow the fuse, the entire fused terminal is $23 dollars and I ordered a new one just in case.

261249


Ran the wire into the cabin via the OEM plastic boot.

261250


Zip tied it in place with the OEM wires.
The run from the battery to under the driver seat is under 6 feet.

261251


As a side note, I was surprised to see what Mazda did to quiet the floor.

I'm going to be installing a fairly small 5 channel amp and had thought about using the stock battery fused post. Glad to hear it's a viable solution.

Man how's the Unity69s coming along? Dying to see what you come up with! Thought about them myself but still had shell shock from trying to mount Stevens Audio MB-8s unsuccessfully. What angle do you plan on mounting them? Diagonal?

nice !!! always have digged your work!! how you like those 6/9 output?
Thanks.
Havent really tuned the system yet. Did T/A and Im using conservative crossover settings to break the speakers in (U3´s from 320 hz and up, U6x9´s from 320 to 80 hz and the sub from 80hz down all with LR 24 db).
Im waiting after break in to do some real tuning, but so far I like how it sounds.
I got to listen to other cars with the U6x9´s (including Ben´s Durango) and I really liked them.
