I believe he is the same guy removing the enclosure panel for me also. I saw the ad with the D/S sub and jumped on him.

Well at least parts from his car will live on amongst the community.

My door belt moulding came from Brian as well.

Thanks To Eddie spotting it on FB and letting me know I now have 1 factory sub box with a TB sub already fitted and the factory grill on its way.
I picked it up off Brian from WA who's very nice looking 94 turbo hardtop had met an unfortunate end " />

I got a start on the sub installation tonight.

I removed the OEM wiring from both boxes and starting making the new harness (so to speak) for the inside of the box.
The connectors I bought from Jaycar required the holes in the sub boxes to be modified slightly. You'll notice for some reason the OEM electrical connectors are significantly different between sides.

Driver side

Passenger Side

After a little cutting and filing the new connectors sit inside the original holes, I'll just need to glue the connectors in once I'm happy with it all.

Driver Side

Passenger Side

The Polk Audio MW5530 woofers installed into the sub housing with zero modifications required which makes it a much simpler upgrade compared to the Tang Bands.

The last pic shows how much room is there for the upgraded wiring and the larger connector.

Initial thoughts on performance are hopeful. You're never going to be popping windscreens out with 5 1/4 inch subs but these little things seem to perform very well for their size. I still need to make more adjustments at the amp but it's actually left me thinking I won't bother with the drivers side for now and just see how this goes. I think I'll be better off spending my time and money trying to lower the cabin noise, that also leaves me retaining the OEM storage box on the drivers side which is perfect for the targa bags.

Nikayla, does your car have the body cutouts on both the driver and passenger side?
I'm thinking that part of the body may have been changed as part of the late 92 upgrades. Which means I should be able to source that panel in Australia.

I will check mine and get back to you on this one, I hope mine has both as it will make it a lot easier to do what I wanted to do.

This morning I decided I would cut the holes required in the carpet for the speaker and port holes. I started on the passenger side, and it all went well.

Went to the driver side, the body is different and won't accept the sub box. I had thought the body had the cut outs and mounting holes on both sides but it appears not.

It's left me with two options;
1. Use only the passenger side sub, which leaves me with an extra sub and box.
2. Find a wrecked LHD MR2 overseas, get them to cut the frame out and weld it into mine.

I spent most of yesterday wiring in my new head unit.

Mounting an Alpine PDX-V9 under the passenger seat.

Wiring the JL Audio crossovers under the drivers seat. These ones I believe.

It's the first time in two years the car has had a functioning stereo.

Everything is ready to go for the sub install, just need the subs to arrive.

Looking like it should be a nice system once its done, pity your not still local it would be good to hear how it sounds once you finish.

I am keen to hear how yours sounds Bill.

I just purchased a Kenwood DDX917WS head unit I have got a Rockford fosgate 4 channel amp but I am considering changing the amp so still undecided on that.
All the gear I am removing from the MR2 is now going to a new home in my newly acquired daily so I can kill two birds with one stone.

I've been keeping an eye on this thread as I've had a pair of boxes for years and never did anything with them.

Last night I ordered a pair of Polk Audio MW 5530, they're discontinued apparently but there's a few sets still on eBay. With similar specs and reviews to the Tang Bands they should be a good option. Also they're cheaper, and fit within the stock housings with no cutting required apparently.

What amp and head unit are you planning to run Nik?

No, it had already had aftermarket pioneer speakers instead by the previous owner which sound quite reasonable So I just want too be able to improve the low end response.
This will also be the 3rd head unit I will have put in it since I have had it and now this one should be the last one as this one should do everything I want it to do.

Nice, are all your existing speakers original?

I think going through their ebay page would be a good option as you can then have cover if they were to get lost in shipping or something. those ones have quite a lot smaller magnet on them don't they! I am guessing no matter which aftermarket subs we went with some form of modification will probably be needed.

Just received my new head unit the other day as well so I am planning a complete revamp of my system.

Yep part-express is where I'll get them or through their ebay page.
The Tang Band W5-1138SM 5-1/4" Neodymium Subwoofer is what was recommended to get as they appear to be the least hassle to install. i.e able to cut through the thin metal frame/mounting plate.

Maybe have a look at this US MR2 thread to see how they install these subs.
http://www.mr2.com/forums...tall-Tang-Band-W5-Subs

I guess you could fabricate a mounting bracket to install the ones you linked, as the frame looks quite thick to cut into.

Well which ever 5~ inch sub you decide to go with there would need to be some sort of modification to get them fitted to the oem box which I'm sure you'll figure out.
