2019 CX-5 GTR Bose Sub Upgrade to JBL Stadium BassHub

[acidbug]

To those who have already upgraded to the JBL Stadium bass pro I’m in need of some assistance.

I own a 2019 Mazda CX 5 GTR. The Bose Base speaker from stock woofer is weak. I’m happy with rest of speakers.

I’m willing to write a sticky with video.

I read many threads and believe we need step by step/sticky. I have the cameras.

JBL BassHub Pro

Powered 11" subwoofer enclosure with 200-watt amp — mounts to hub of spare tire

* Also need wire kit for the built in amp.*Also, the OEME screw down is not good enough.

* Also, how to get the connections from the OEM wiring for factory sub to integrate to the new JBL sub.

Anyone in the Central New Jersey area that have done it & could assist would be greatly appreciated?

Thanks in advance,
C

Some info from another thread:

Good news, JBL hub fits with half inch of space between the cover. Bad news, screw rod needs to be cut an inch. No biggie, an easy fix. Can't wait to get this baby installed

If you have a 17 up with bose, you would need to connect/t-in something that will take the low level, unprocessed signal from the TAU before it gets to the amp. Otherwise if you grab the amped wire for the sub, it will be a modified signal that won't sound good with anything else as it was tuned just for the Bose woofer.... It can't produce really low frequencies and Bose made sure that it wouldn't see them... I am just glad you tied in at the amp instead of the connector at the sub.... You would have been very dissaponted.

So you have the bolt screwed all the way in/bottomed out, yet it isn't making contact with the new sub?

If so, then I would NOT cut the bolt.
Just go to the hardware store and buy a large washer and rubber grommet(s). Slide the grommets over the bolt, then the washer. This will preserve the bolt, secure the sub, and the rubber grommets will help minimize vibrations.

Some additional info regarding wiring in plug and play.

Guide: - 2017~2020 CX-5 Add an Amp Adapter

I originally posted on Mazda6 forum but thought you guys can use this guide too. This is for the 2017+ TAU with the new small 20 pin connection. This will allow for adding an amp without cutting of any of the stock wiring and completely removable. Parts used: SCOSCHE NN04RB Reverse Stereo...

Ps - to some degree there will be some bass roll off even wiring in before Bose amp ( cuts around 45hz approx from head unit) I am afraid the only way around this is either use a DSP or drastically change head unit !!) I opted to fit an Helix DSP and set up via their software supplied. Just depends how low you want your bass - 30 - 35hz this probably the options available - there are loads of discussions on the forums per the use of DSP,s and there is also a video review of the Helix DSP on YouTube

The amp on my ‘19 CX-5 Bose system, the amp is located under the passenger seat. Have to remove the seat. 4 bolts holding down the rail system for the seat.
Then there is a cover to the amp…be sure to pull correctly as I bike 2 tabs (repaired with super Glue).

I believe the amp harness closest to the rear of the car is where the connection is for shares usage with the sub. Need to splice into or order plu and play harness. I’m looking into it and see if it’s cheap enough and still being made.

Someone mentioned the 65 Bose subwoofer amp is located in the trunk. I was unable to locate it.

I plan on using AudioControl LC2i for 2 channels to clean up the signal. So I can get those low base frequency the system cannot accomplish (due to programming) & the small speaker in the OEM sub.

Plan on using the dials on the LC2i to base line and then fine tune adjustment from the Jbl sub to lower/increase the base depending on the song I listen to.

Anyone in the NY/NJ that can help me. PiZza and beers on me!

So I've re-thought the creation of a simple connector to tap into the preamp signal going into the Bose Amp under the passenger seat.

I picked up the Scosche NN04B connector kit. But, it seems like a bit of overkill and a rats nest to deal with, just to be able to return the vehicle to stock someday

I also don't want to cut, twist, solder, and heatshrink the factory or scosche wires. Besides being a pain in the ass, I know the finished product won't be up to my cleanliness and simplistic standard.

So, today I just found out about Wago connectors. (yes a bit late in my discovery, as they've been around for a while)

They're certified for home and automotive use, and seem to be an excellent way to cleanly and effectively tap into the preamp signal. Also, there is very little resistance difference between connection styles according to this video.

So, cut the factory preamp wires and splice into the 3 wire version, input and 2 outputs, simply with 8 connectors for the 4 channels (or 4 connectors for 2 channels).

Can anyone confirm the diagram for connector 0920-515A from the Mazda 6 in-depth research is correct?

Simplified (specifically top box connector 0920-515A):

The 2024 Mazda CX-5 with Bose has different color connectors and different colored wires in different locations from my 2019 CX-5 with Bose. Here are some current pictures of the above from my 2024 CX-5 at the amp.

If anyone knows which connector is for the audio or has a correct pin out of the 24 Bose system, please let me know!

I want to wire in before the amp.[\B]

I purchased PAC APH-GM02 from Crutchfield and the connectors perfectly match (connect at both the harness and the Bose amp) on my 2023 CX-5 Sig (so no need to cut factory wires). Connector & wire colors do not match the factory connectors & wires at the Bose amp.
*got delivered with 20 minutes of lights left today and only had time to check connectors and colors before it got dark.

Upcoming days I will spend some time and figure out if this is a viable option for Mazda CX-5’s with Bose Amp…
which connector is for line level rear/front speakers and if the wires trace properly/match the OEM wiring harness. Will report back later with more information.

Wow, well done. Interested to hear if this works!

I currently have mine tapped off the factory sub, it works... But could be better.

Teddymac What year and trim Mazda do you have?

Which connector/wiring harness did you tap off/on? At the amp? Did you tap the left and right speakers at/before the amp (at the wiring harness under the passenger seat)?

Did you take any pictures?

 

[acidbug]

I got this from Crutchfield. Page 4 of 5 details the connections at the amp.
* please note this is for a 2023 and above CX-5 with Bose.

21 carbon with the Bose system. I just tapped into the sub amped-signal with some wago interconnects into the high level input on my amp. It definitely adds some good bass, but the signal is definitely tuned for the factory Bose sub.

I came to the conclusion that my car must have the updated TAU, as it has different connectors than the post for 2019s that I made the T harness based off of.

It would be nice to be able to get the signal pre-bose processing.

After taking some time to review the schematic - I believe the audio signal is through the optical MOST Bus connection... not low level RCA like older models.

This poses to be an issue to pull the audio signal from, without additional devices.

I was reading on another thread and they were saying that the blue connector all the way on the left is actually can bus optical audio from the Bose head unit to the Bose amp. The connections that we are tapping into/on are the outputs to the speakers, etc.
