Yes. I did this two months ago with a Becker Mexico PRO MD. Wonderful gizmo in every aspect. Best stereo I've ever had. Anyway, the easiest place to hook up with the speed is by the fuses. Unfortunately I don't remember the exact placement of the wire, but along all the connectors and wires in the lower part of the fuse panel, about 2/3rds to the right end, at the top of one connector, you have a red/brown thin wire. Just hook into that one and your GAL input will be happy. Let me know if you need more info, help, of a procedure to very that it's working (unless you already figured that one out). And me personally, I've found that GAL 05 is about right. :-)

I'd recomment you start by using that standard amp and see how you like it. I am, and I really don't understand all the complaints about power. With the Becker, the sound is *great*. I did have problems with power using a Sony unit previously though, which makes me wonder about how standard pre-amp outputs are...
