Nice! I was close to getting the DLS Nobelium 2-way components when a former Z owner approached me about speakers he was selling.
How deep is your subwoofer? If you can fit it in your MR2, then it'll fit the Z. You should have enough room to fit a single compact 10" subwoofer in the strut bar area (13" depth flush). Behind the seats are small "cubby" holders. If you have some compact devices, you can mount them in that location.
