Hey I just bought a RHD 92 RX7 recently and was wondering if these parts are still around for the rear system and right side (driver) door. Looks like the rear amps are bad as they are completely rusted out and I suspect the right front amp is also bad.
Any way to source these or is anyone selling one? The part number I found for the rear amp is 146034-6102 but coming up empty on google. Thanks!
I don't know if they are still available new, I would email Ray Crowe and ask him - Crowe.ray@aol.com - you just need to describe the parts, he can find them in the system.
That said, I'm sure these shouldn't be too hard to find used since so many people tear out the Bose system. I know there was a company that repaired Bose amps as well, that may be worth researching.
They almost certainly won't be available new from Mazda/Ray.
Your best bet for new would be to contact Bose Automotive directly. I believe they still have a customer service number on the bose automotive website.
I wouldn't hold your breath as they were pretty low on stock with no plans to replenish a couple of years ago, but they may still have a few sitting in storage somewhere, or might be able to cross reference the amp to another that would work.
If they don't have any, repair would be your next best bet. There are many places that will try to overhaul these amps for ~100/amp (at least at the time I checked, which again was a couple of years ago).
Just recently redone the stereo system in my FD that has the Bose Acoustic Wave. If you get no joy finding replacements or repair of the amps, you can install a modern head unit with an inbuilt amp and bypass the speaker amps to the speakers directly with a little rewiring. The system still sounds good with the amps bypassed.

I would caution against this. I forget the exact ohms that the bose speakers are, but they are not a standard impedance like off the shelf aftermarket speakers are, which aftermarket headunits are designed to drive.
You would be better off selling your remaining bose components and installing aftermarket speakers/amp(s) than feeding the bose speakers directly.
It's only the heat shields that are rusty, but there might be rust elsewhere in your hatch if that occurred.
It's super easy to repair Bose boards, most likely your caps are blown.
Here's the digikey.com parts list, you just need to know how to solder.

Pretty rare configuration. S7 spoiler must be a later add.
My main parts car was a Type X automatic (SSM/Black leather) Is yours a conversion, I wonder?
Car had a number of hidden features, such as extra thick sound insulation in various places, including possibly the main cabin carpet and fire wall insualtion.
The automatic air conditioning unit was pretty rare in JDM versions, I believe.
Sorry, I just remembered when I was looking at repairing or replacing the amps,
If you would rather retain the stock setup, it turns out the same amps were also used in the Nissan 300zx (Z31-Z32 Fairlady). You could also give Nissan a try for price and availability?
Pretty sure the complete speaker boxes are the same units as well.
Apologies guys I didn't have notifications setup for this account, I probably set this up like 20 years ago lol.
Thank you so much for the replies, I'm going to review each and see about maybe going the repair route.
Is that amount of rust not normal on a 30 yr old car? I've noticed a bit of surface rust behind the head unit but all looked to be within a normal amount for the age.

Yeah that looks def like mine - not sure about the conversion but the seller doesn't think one was done. Might be one of the extremely rare manual type Xs. I can confirm an incredible amount of sound deadening. Just ran an amp wire for a bass tube and had to poke through it.

Nice looking car and also nice garage floor!
You are in So Cal? How are you registering a JDM car?

Hah thanks the floor was like that when I got the house, just moved in 3 months ago. They're just stick on tiles, does it actually look good?
Going the Montana route as the seller already imported it and had it titled there already. Look up creating your own LLC to register vehicles in Montana.
So just replace what looks broken and hope for the best?
Unless you are VERY good with electronics I wouldn't consider getting out the soldering gun and just hacking at it. That's an easy way to make a small problem a much bigger one.

yup there was like a 1% chance I would try that. I can see the circuits they look very easy to work with, but if anything I’d have them professionally refurbished.
I'd still recommend reaching out to Bose first. I paid less for new amps from them, than it cost to repair old ones. They will also have all the cross references for amps in other cars that might work.
At worst, you're out a 10 or 15 minute phone call.

Appreciate the info, I got a little impatient and went and did a thing -
Took out all of the bose amps and speakers, utilized the wiring in the doors w/ adapters for some alpine 6.5" type Rs. Ran power, turn on, and RCAs for an alpine bass tube w/ alpine 500 watt amp. All ran by a 7" pioneer touchscreen with wireless apple carplay. Now it's time to put humpty dumpty back together again lol.
Looks good to me. I'd just be mindful of how thin the factory wires going from the radio to the amps are, don't want to push anything that's over their limit.

Yup, just reusing factory speaker wire running directly off of the head unit to the front speakers, looked to be 16ga and the head unit is only putting out 50 x 4 watts peak, 14 rms. All the amp stuff is brand new run direct from the battery RCAs off head unit.
