Does anyone know where to source the FX one tower speaker brackets for JL 8.8’s?
Also, are the FX one towers pre wired for the second set of speakers?

After doing some research, the brackets are not available and are Supra specific.
You also can’t but just the brackets from SC, you have to buy the whole JL 8.8 speaker with integrated FX one brackets.
So custom brackets it is or pipe mount as close to factory location.

Or buy a new 2020 SA with 4 tower speakers and 2 12" subs :cool:
That just might happenQuote:

FX one towers are pre wired for both sets of speakers.

Also uses an amphenol 06-6s connector.

I recall reading a few posts on social media about this. Someone was talking about a 17 and the wires zipped tied to the rest of the wires where they entered the boat from the tower. The person had to connect new wires to run them to where they wanted.
Sounds like you started taking things apart.
Yep, it’s happening. Just need to find other end of speakers wires.....I am hoping they are behind the amp mounting board.Quote:

My current 2 tower JL8.8’s are run through a M400/4 like this.

I am swapping the M400/4 with a M800/8 like Supra does from the factory.
How should the M800/8 be wired with 4 JL8.8’s?

What amp is running your cabin speakers? If it’s an 800/8 you might could use that 400/4 for the 6 cabin speakers and the 800/8 for towers.
Sent from my iPhone using Tapatalk
Cabin and sub already running a separate M800/8.
Current 2 tower 8.8’s run on a M400/4
Supras with 4 tower 8.8’s run on a M800/8, I just don’t know how it’s wired?? How many RCA’s and do I bridge all 4 towers over the 8 channels?
Sent from my iPhone using Tapatalk
1 input for rca. Basically wire just like picture but four times instead of two. Should be 200 watts at 4 ohm to each speaker. If you hadn’t already bought another 800/8 that 400/4 would have ran cabins.

So I should transfer the 12v, ground and remote, 4RCA’s, and bridge all 4 tower speakers to the M800/8?Quote:

Yes transfer everything as is. Put those rca’s in just like they are now and choose 4 channel input on the switch. All 8 channels will use those 4 inputs. Be sure and tune the gains.
FYI 60 hz seems off for tower speakers to me.
Sent from my iPhone using Tapatalk
What do you recommend for hz? 60hz is the factory setting from Supra.
Sent from my iPhone using Tapatalk
This is certainly up for debate and different speaker amp combos make it even more debatable. Try this and see how it sounds.
Sub Low pass at 80hz
Tower high pass somewhere around 80 to a 100
Cabins high pass 100
Progress.....
Speakers installed on tower, had to use JL pipe clamps as Supra FXONE tower clamps are not available to aftermarket. This offsets the inner speakers slightly rearward, but I like the look.

Tower is wired and speaker leds and down firing lights were all plug and play with factory Amphenol connectors.
Traced factory speaker wires looking for the ends for the inner speakers to wire to amp. It’s not fully wired from the factory for all 4 tower speakers, but very close.
There are two Amphenol connectors that are 4 pin for wiring from the tower but only 2 output pins are hooked up for 2 speaker boats.
Easy enough to add wires and two more pins for the new speakers. But about 80% plug and play using factory harness.

Speakers and amp fully installed and ROCK’nnn!!!
Thanks to MLA, Knoxmojo and Russelsmojo for helping an audio newb.

Are you wanting to sell the 4 channel amp?
I'm getting ready to do the exact same thing. I purchased 2 speakers and brackets from someone upgrading to wetsounds. They will match my existing 2 speakers perfectly. So what do i have to do about wiring? The amphenol connectors are there in the tower. What wiring is required on the other end?Quote:

If you have factory speakers it’s much easier.
The Factory plugs at the speaker side should be plug n play.
Climb into the starboard dog house and find the speaker plugs. I had to clip a few zip ties and you should get enough slack to work on them comfortably.
Then it’s a matter of running two left side wires and two right side wires and attaching to your new amp.
Did you get a JL 800/8 amp to run your 4 towers?

Great topic. I've been thinking about this upgrade in the future, maybe next year. Just planning on cost. The instructions you all provided seem pretty clear, straightforward, even for someone who has never done this before, like me. So this is great info.
Quest:
the speakers you added do not have the down firing LED lights. I found these at Crutchfield:
https://www.crutchfield.com/S-9S12cS...yABEgLESvD_BwE
Is this what u used? Did u find the ones with the integrated down firing LED's anywhere.?
The brackets in these speakers are round, I'm guessing I can remove them and install the angle brackets u mentioned, or did u get a diff speaker altogether.?
The amp I found is this:
https://www.crutchfield.com/S-KX7BFI...iABEgLE6vD_BwE
So I'm guessing a total cost of <2400$, including the aftermarket angle brackets.
Does this all sound about right?
Unlike the Moomba, I plan to keep this boat for a looong time. (Under spousal threat). So I bought it with plans of slowly adding DIY upgrades over time. Things such as this, a second set of racks, prop, Phender Pro's, et. al.
You can use the aftermarket JL 8.8’s with the JL tube clamps. It takes some additional work but I actually like the look of the finished product. I personally like the center set being slightly offset. Gives it some depth.

You can also add the JL downfiring LED tail cones to match the factory ones. You order them right from JL website. I think I got them on sale for $150
You can also buy the Supra specific version of the JL 8.8’s, it’s the only way to get the factory speaker mount. They are $$$ but are truly plug and play.
As far as the amp, your 2020 has the newer JL
mvi amps, the 800/8i is around $1200

For the cost, an amp like the Wet Sounds Syn-DX2 or the Kicker KXMA1200.2 are far better then M series 8 chnl bridged into 4. WAY too many RCA splitters required to make it work correctly. The Syn-DX2 is going to deliver similar wattage and only require a single pair of RCA. The KXMA1200.2 is going to also only require a single pair of RCA and yield a ton of wattage head room.
holy paycheck batman...... $1200+ for that JL amp is insane.

Right or wrong, I wanted my system to be like the factory set up.

If you populated 4 RCA on an M800/8 bridged in 4 chnl mode and its one volume zone, then there is an RCA split somewhere. To make the most of the M800/8 in 4 chnl mode to 4 full-range speakers, you have to populate all 8 RCA inputs. JL's own engineers state this, its in the amps manual as well. This is also common with bridging many other full-range amps.Quote:

Not sure on splitters but it’s wired identical as the factory 4 tower speakers.Quote:

How did you insert 2 new speaker wires into the Amphenol connector's open pin slots? Is there a special tool to do this or do you just shove them into the connector? I've located the connectors and they have 2 open slots, just don't know how to make connection...Quote:

Then it’s as simple as crimping pins and pushing them into the existing connectors.
You could also skip the Amphenol connector and just crimp wires direct using a butt connector.
The only reason they use Amphenol connectors is easy of manufacturing.

how did you attach 2 speaker wires from amp to the factor connectors in the dog house? the factory connectors are 4 pin and have 2 pins open for new wires. is there a special tool that inserts speaker wires into connector?Quote:
