For simple up/down volume control, is an L-Pad the best route? Also, this will be a 2 speaker stereo system. Do I really need a stereo L-pad or can I just use a mono L-Pad and wire leads from both speakers to it to simultaneously reduce output volume to both?
Thank you in advance

No an L-pad is not what you want. You need a variable wire wound resistor aka a rheostat or potentiometer. I have to leave so hopefully someone will sort this out before I get back
I am hoping someone can help you more than me. The way I understand it, if the volume is going to be low, you can use a dual gang potentiometer, but if this is for full volume stuff, use a dual gang rheostat.
It's a bit easier to reach over to the system and turn the knob than waking the MP3 player and using its internal volume.
An L-pad is for reducing the volume of a tweeter, and it retains the correct input impedance (e.g. 8 ohms) and at the same time gives attenuation. Constant input impedance is needed otherwise the filter will not work.
Only when you have two stereo amplifiers you can, with a separate volume control, reduce the two tweeters at the same time. That is a costly operation thou compared with an L-pad (costing somewhere between use 20-30.)
