I have a cerwin B4 amp for my bike that I just went to put in yesterday, I have a PAC 35 (i think) box but it only has one set of left and right RCA plugs, my question is do I need two of the PAC deals, one for the front and one for the rear? this is on my 2002 ultra with the stock radio.

 

If your radio has two sets of outputs you can run two PAC SNI-35's and keep your ability to fade from front to back, or you can get by with one PAC SNI-35 and run two RCA Y-adaptors to get your trip sets of RCA's, but you would lose the fader option.

 

thank you for the info. guess I will order another one.

 

And just to double check, does the radio it self have RCA outputs?

 

no it does not
