Speed controlled volume?
Can anyone here tell me if any of the Alpine HU's have a "speed controlled volume" feature? Sometimes referred to as "speed sensitive volume". If so can you tell me models number(s).
Thanks,
Robert

Sorry bro,
Most aftermarket system don't have "speed sensitive volume" because of other complex systems being used in vechiles. The way speed senitive works is there is a resistor in the bose amp that since the static elec produced by the engine thru the rpms. No these is peculiar to each car so aftermarket manufactures would have to know the operating engine speed in all cars do this with good results. Hope that helps.

I thought the Bose used an input from the VSS on the serial data line via the PCM. Oh well, guess I'll just have to give up this feature when I go Alpine HU.
