Well, I installed a Sony MP3 CD-Receiver this weekend with Infinity Reference 3.5s under the dash. I mounted them without the brackets (the truck had a mono 4x10 in the middle of the dash), but going back and using brackets at some point would be preferred. Right now I drilled a hole for 1 corner of each of the speakers, so they aren't mounted as well as I'd like. To get the hole drilled for the driver's side I removed the gauge cluster and drilled upwards through the dash. In doing so, I also cleaned a bunch of the dust from behind the dash/guage cluster. The stereo sounds very good for what it is. Now I'm waiting on my 6x9 speakers to come back from the wrecked 944S. I plan to mount the speaker boxes to the wheel wells next to the rear seats, which should even out the sound.
