It's been a while since I was really into car audio but I was there when the stuff first came out and got to watch the progression until the DB Drag stuff started then I was pretty much out. Everything seems optomized to run at 2 ohms and in some cases even lower so I think that had a lot to do with it, that and the poor quality of the designs. I remember when you opened up an amp it was full of componets then a lot of cheap manufacturers would use IC amps like in Brians design to drive their output stage directly and the specs on those are not the greatest the quality suffered as well. The only one I knew that had anything close to a quality amp was Matts they used the LM10 and 12 to drive their output stage and they were pretty good. About a year before they came out I was looking through the Digi Key catalog (when it looked like a magazine instead of a phone book) and ran across that chip and was like that would be great to run straight to the output stage. Well that IC was about $75 and I didn't have the money to get one (If I knew about samples back then

) I would have taken that and the TIP 35/36 and made an amp while I was still in highschool. I ended up making an amp when I went to tech school, but that one used 2 2N3055's for the output stage.

Ahh memories.
