Answer 1

Wire the LEDs in parallel, not series.  

Are you sure that the speaker outut is an RCA jack?  Try connecting the LEDs to the Tape Out rca jack, it should have a constant 5V.  The problem you may run into is that there won't be enough current.  

Also, if you use a speaker output to power the LEDs you could end up smoking them because the voltage and current could get too high.
