Matrixowners.com might have a how-to, but the site seems to be down ATM. There honestly wouldn't be much to build, other than drill the hole to flush mount your tweeters. If you don't want to drill a big hole, then you can drill a smaller probably and just surface mount them, but flush will look better. Then, just replace the OEM door speaker with the new component woofer, wire everything to the included x-over, and you're good to go. Aftermarket will sound better than OEM any day of the week and will last longer than the paper cones on the OEM's.
Here's a good instructional video. It's not a Matrix, but the installation is pretty much universal.
