Holy Bass! That must have been a nightmare to fit.

What size is it?

I cannot recall if it was a 10 or 12 inch. (oh and despite how it looks that isn't rust behind it!)

It ended up being too much and we scaled it back to be dríven by a small amp and running higher than usual frequencies through it too, not a typically "good" idea but for the small cabin and high amount of roadnoise it was an acceptable solution for me, kinda tried it cause no-one else had and the tank was out anyway.

but def will be going with the 2 8inch drivers!!

If you get stuck let us know, pretty sure I would have more detailed pics somewhere.

I still think the two 8 inch set-up is the way to go, having said that Benny's SP sounded superb when I heard it a few years back and it has a neat boot install. FWIW I rack up ten hours in a laaaarge car once or twice a month at the moment, no modifications to the factory fitted premium sound package and it is exceptionally good, sub bass is via just two 8 inch woofers fitted to the parcel shelf, so again, I reackon that's the trick in an MX5, even keep the carpet uncut to hit the install.

Can't say specifically about that install, but mine in the same place didn't need any cutting. Just the unbolting of a metal cover.

Definately not in the same place then.
I watched as the nibblers cut away at the metal and the new support was welded in!

Each or as a pair? Either way you don't want to know what my ID8 was worth...

As for research, go to a car audio store and have a listen to a couple of different sets. Trust your ears, not interweb fourms.

Hmmm, maybe thats why I was encouraged to go with the 8"

It's likely.

The 8s will easily fit in the removable alum covers, and they probably provide a more balanced sound too.

Clearly the picture shows I was young and only interested in doof at the time.

Just curious, when you guys do the bigger scale boot installs, what do you do with the spare tyre in the NA MX5's?

I'm doing a high end competition install in the next couple of months, and I've found a way to get around the spare tyre (by simply installing around it) but at first I was trying to relocate it somewhere and couldn't find anywhere to move it to.

In some of these pics it seems like the tyre isn't there at all, so just wondering if people have just removed it completely (is that legal?) or somehow relocated it?

No matter how you tune the sub in the cabin, if you wanna play your music loud like most people do you wont be able to stand it. The sub has to stand out a little bit, and that constant bass from the cone would drive you insanse.

Not true at all.

If you design the system for sound quality and tune the sub accordingly (so it's at the same volume as your speakers) then the sub won't drive you insane at all. Human hearing is more sentitive in midrange and high frequencies, we 100dB @ 2khz is actually much, much harsher to our ears then 100dB @ 1000hz.

I got rid of my spare all together and just kept one of those "tyre in a can" things in the glove box.

There have been people who managed to mount a full sized spare wheel under the boot, I'm pretty sure there were details on miata.net

That's the type of thing I had in mind - is it legal though?

I heard / read somewhere that those kits are only legal for cars that came from the factory without a spare, but I haven't been able to confirm the precise laws on it.

I'd like to get rid of the spare (it'll be useless when I change my rims anyway) but that law continues to bug me. Last thing I want is to get pulled over and defected!

It's an interesting question and one that I cannot answer with conviction. I had my car passed through rego thrww years in a row with no spare, but that doesn't mean a lot. I also got it passed NSW enginners and the car was never defected despite being pulled over a few times.

I know it's a defect to replace run-on-flats with normal tyres unless you add a spare, although if you can get an enginner to approve it with regard to teh relevant wheel and tyre size ADR you should be fine.

Don't quote me but I belive the law says that you are free to remove your spare. If you keep it you must however keep it in good condition, pumped up, etc.

I know Trader relocated his spare under the car to free up space. You could try shooting him a pm.
