I upgraded my audio to the Rockford PBR300x4 amp and Rockford t165 speakers in the dash and lower fairing. I have my Hogtunes amp powering my rear tourpak speakers. My problem is that up until I unplugged all the front wiring to the Hogtunes amp my rear speakers played. I have a feeling that the wiring may need terminating in some fashion to work.

What can I do with the front amp wiring to correct the situation?

 

Just got an answer from Hogtunes. Seems that the amp is not bridgeable. I had changed the mode selection from 4 channels to 2 channels hoping to get 80watts per channel at 2 ohms going to those rear Hogtunes speakers. It has to be in 4 channel to work. Oh well.

The other alternative is to pull Hogtunes out all together and find a small 4 ohm amplifier to push some nice 5.25 speakers back there with the bass ports.
