I have an amp that I purchased off of the for sale section here. I have a 2006 RG with the Hk radio. When it comes to audio and wiring I'm an idiot. I noticed the amp does not match the wiring harness on the the back of the HK radio anywhere. Is there a way to use this amp with this set up. I should also point out I upgraded to the j&M speakers. Any and all help is appreciated.
