They are these. http://www.clearwateraudio.com/cwc3d.html
The "Fiero ones" just had the pigtail with stock type connector attached,
and of course, you didn't get the Mazda wiring harness.

Hey Fierosound, great writeup and thanks as always for sharing your vast experience with fixing the tinny audio in our beloved cars. I did want to point out that using the term "bass blockers" for a capacitor is way inaccurate for what they actually do. A capacitor only reduces the level of the AC signal at a given frequency by 6db per octave below the initial cutoff frequency, also known as a first-order crossover. It's simple and it has essentially no phase or other distortion. But it's more of a rolloff than a total block. For example, say you've got a capacitor with a 120Hz cutoff frequency. You have an input signal that's a flat 90dB across all frequencies. At 90Hz, you'll be down only 3dB at 87dB. At 60Hz, the first full octave, you'll be 6dB down at 84dB. At 45Hz, you'll be at 81dB, and at 30Hz you'll still be at 78dB. That's still a lot of bass going to those speakers.
For something closer to a block, you want the steep rolloff of 24db/octave or fourth-order, as is used in active crossovers. Fourth-order passive crossovers can be done, but they are very difficult and expensive to build.

Sounds like an ideal alternative to the hard-to-find Xtant 1.1i amp.[This message has been edited by fierosound (edited 03-29-2011).]

Thank you. 
If the dash & interior is out - soundproofing and subwoofer.
Other speakers and radio can be done anytime without dismantling the car.[This message has been edited by fierosound (edited 04-21-2011).]

Hey fierosound,
Fantastic writeup and I've read it a few times now. But I must ask... do you have any suggestions for those of us who have no access to the appropriate componentry to install the factory subwoofer enclosure? Would love to give my system a little more fill, but being that there's zero parts availability here and my car's converted to RHD, there's not really any way I can do the stock enclosure. Was thinking of one of those underseat type sub/amp units, but I have my doubts about the quality of such contraptions.------------------
