After weeks of reading thru these forums for tips and tricks(yeah i been cheating lol) i just officially signed up today. One of the best forums ive been on. But im having troubles after deciding to upgrade my radio on my 02 ultra limited with JVC x33mbs radio and scosche thumb controls only have sound in front speakers as the controls dont even have speaker lines to connect to new radio harness. Now that said i do know there is an amp under tourpack (radio sound 55x4) that i was kinda hoping i could reuse that for now to see how it sounded in the mean time. Any help would be appreciated in the right direction!!!

 

does that head unit have 4 or 6 rca outputs in the back?

 

It has 6, 4.0 amp rca outs

 

if you scroll thru radio settings is there a selection for rear/sub?

 

Yes for both

 

select rear

 

Tried that didnt work, it seems like the factory amp is not recieving anything actually from wiring harness on bike. Works fine on factory radio when plugged in to both harness.

how did you connect new head unit to amp?

 

I just wired up RED power, BLK ground, YELLOW constant, BLUE steering wheel control to BRWN wire on hand controller adapter, along with front left GRAY and WHITE right speakers. There is a set of GRN and PRPL coming from radio harness for rear but no rear wires from thumb unit. So i plugged it into brake side factory harness powered it up came on controls work just nothing from the rear pods. i was assuming that amp was running off hi-input lines since there was no rca cables coming from original radio and rear amp uses same type of factory plug as front.

 

which thumb control unit do u have?
