I used Alpine SPS-400 for the dash speakers - the passenger side one was a bit of a challenge to fit due to depth. I wired the rear deck without cutting holes. I used cabinets to mount a pair of Kenwood 6x9's that I had on hand. I will eventually replace these with an Alpine component set in smaller cabinets.

I do not have a fader installed. I have the Becker part and wiring figured out; reluctant to cut the console to install it. I also do not have an amplifier other than the primitive one behind the glovebox (part of Becker Europa II).

The sound is great - no cutting - options to modify and replace as technology evolves.
