Discussion from 5th Gen re: XM radio install evolving into XM modulation

Question -

Does anyone know if you can stack multiple FM modulators to feed multiple signals (say modulated ipod and XM) into stock radio on different frequencies - or do they make a modulator with multiple inputs that sends two frequencies to the antenna output?

I know some of the modulators kill the antenna input signal, which is a good thing for sound - but it would probably prevent stacking modulators in series.

 

I've never heard of stacking modulators, but couldn't you just use a Y-adapter to branch off your single input to the modulator into two inputs, and then just shut off whichever item you're not listening to (iPod or satellite)?

 

Thanks BigDu - don't know why I didn't think of that....

leave it to me to come up with a complicated process when there's a simple solution.
