Go to this thread https://www.clublexus.com/forums/sc-...enna-woes.html and grab the PDFs in the third comment... your only issue will be the 8ohm speakers

This thread has everything you could ever ask for about the SC430 speakers, sub etc. How to replace. What to replace with. Wiring details etc. etc.

Agreed. If you have the cash, it would be nice to replace everything. My dream system would be Boston Acoustic for the two smallest sets speakers, Polk audio for the smaller front doors and infinity kappas in the rear powered by a JL sub and amp.

I'm in the process of replacing my speakers. I removed all the panels and seat cushions to remove the speaker drivers. These speakers really are a piece of crap. I've seen heavier magnets on kid's toys. I can't imagine people rebuilding these by replacing the foam, etc. If they're a piece of crap to begin with, you'll have a bigger piece of crap when you're done. I have ordered the DC Gold as mentioned by many others for the front speakers.
The sub is extremely wimpy also. There is some depth, however, the hole is encumbered upon the bottom side by some metal support for the trunk. A speaker with any larger magnet hits this metal at the bottom. The 8" 16 ohm woofer I purchased has a much bigger magnet and will not fit into the stock hole using the same mounting hardware. To answer an earlier question, it's not so much the depth as much as the diameter of the magnet. However, it seems fairly easy to construct a raised mount (think of a giant washer) to move the woofer towards the inside of the car. There seems to be enough space carved out of the seat back cushion to allow this. I'll know more in the next couple days as I refinish mine.

Thanks don let us know your outcome, I purchased an 8" kicker 4ohm sub (im going to bypass the amp for the subwoofer) that I'm hoping will fit in there, its only 4-1/4" deep but took the trunk and back seat apart today to see what in was working with and can see where you would run into toublr if. Magnet is too big diameter wise. Speakers should be here soon will lt you know.

OK, I'm going to have to eat crow on my earlier post. The new sub driver's magnet was way to big to fit in the stock opening. No problem, just make a spacer ring to bring the sub out, right? Well, I connected the new driver up to check it out and it barely moved, hardly any sound at all. The amp is way under powered for this new driver. So I involved the help from a local shop that obviously knows what they're doing (at least more than I do) and they said there is no driver they know that will work. They suggested either changing out the amp and driver (which is what some have done), buy a new driver from Lexus, OR send the driver to be re-built. I was reluctant about a rebuild, but once I visited the reconing store, I was convinced he could re-build it better than original. He not only replaces the foam, but also the cone itself. I dropped it off yesterday and should be able to pick it up tomorrow <insert embarrassed face here

That's funny, I can't imagine the amp necessary to power that thing. If you're remotely serious, you would need a spacer ring about the depth of the speaker, but then it wouldn't fit using the stock seat back. The driver I purchased needed about an inch spacer to make it work. But I sent the speaker back today. I also picked up my rebuilt ML today. It's just like new and will probably last a lot longer than the original, it works and sounds as good as I need it to.
I am serious, just had no idea how much room is actually behind the mounting wall. I'll pop my covers off and have a peek in the near future. I've been wanting to do it for a while now, but don't want a box in the trunk or rear seat, so replacing the existing one is my only option. Could always reverse mount it and cut a hole in the seat haha.
