Z3 Sub box with 1 sub, anyone have one kicking around?
 
I just pulled the sub box in my 1999 with the HK business system and it is the two sub configuration. I had hoped it would be the 1 sub box so I could drop the kicker in there and be done with it (I really DO NOT want to build a custom box for this).

Anyone out there that has done a custom box and has the original 1 sub box willing to part with it? *Or* does anyone know of a write up (I can't find one) of how to modify the two sub box to accept one 6.5" sub? (not holding my breath on the second one :)

Thanks very much !

I think you are several years late for this. The single-speaker sub boxes are no longer available and have been bought-up by users making this same retrofit. It's pretty rare to find one now.

There is not much chance of retrofitting a single speaker into the 2-speaker box. The remaining holes are too large and in the wrong places.

You can replace the two speakers. If you're using the stock amp, just use two 5 1/4" 2- or 4-ohm speakers. (The originals were about 3 ohms). If you have an aftermarket sub amp, use two 8-ohm speakers wired in parallel with reversed polarity to create a single 4-ohm channel. (You have to reverse the polarity since they are mounted back-to-back).

Or you can make a sub box. It's not that hard. I made one out of fiberglass:

Thanks very much for the link :) It does still look like a lot of work. Hmm... At least it's January and I have some time to think on this.

Ok thinking done. Gonna pop the stock sub back in and leave the car be. Ordered a new head unit, 2 channel amp, front speakers, and an infinity basslink powered sub. Came in under budget of $750 at $660 so I'm happy, and should be easy enough to install everything in an afternoon.

Now to scour around the forum for wire designations so I can just use the stock stuff. I'll be thrilled if I can get away with running minimal wires....

Here's what I have on the two different layouts, color codes translated to English, illustrated, and connector pin designations as well.

Not my work, but from a very industrious and helpful member on the other forum. Given the current requirements of the stock speakers/amps, the existing wiring will be fine. All the existing wiring is twisted-pair too so it is resistant to picking up noise. I upgraded my fronts to 85W per DRIVER on my components so I ran 16ga back up front from the new amp. The sub wiring in my '01 was already around 14ga, so I used the existing wiring for a 250W amp (about 8A at full output).

This is great, thanks very much!

Too bad, I have a sub box from my roadster that I'm not using.

2000 Z3 in need of a custom Subwoofer box for 6.5"
 
Just purchased a 2000 Z3 2.3. Has original everything & I want to desperately upgrade the sound system. Seems I will need a custom box to upgrade rear speaker.
Anybody got one they want to sell?

No. The 2000s had the more desirable 6.5 inch subwoofer. Just replace it with a Kicker ComptVT65.
Of course you probably need all new speakers and an amplifier as well.

Blacklane, got in and did some checkiing on my Z's speakers. Looks like the Subs are dual 5 1/4s.

Been looking at just replacing the HU and getting the BSW package. Still will need the rear Subs though. Any suggestions?

Yes, it will. You might have to make connector changes, but the enclosure will drop in and use the existing screw locations.
