Gaurav Posted May 15, 2017 Report Share Posted May 15, 2017 After lot of research and reviews check, I finally got the Pioneer GM-D8604 Amplifier for my Pajero to have better sound signal and bass boost. Got it installed professionally with correct cables and connections at Barry's garage. After the installation we played with back panel setting to configure and realize that AMP is only sending sound+bass signal to channel A (front) and only bass signal to channel B. To eliminate the doubt of wiring goofup or exploded rear speaker, we swapped the channels wire and then we got reversed reaction that bass comes from front and all perfect sound+bass comes from back. How I do best configure this AMP so that all 4 Speakers (both Channel A and B ) delivers Sound+Bass signal at best strength. https://www.pioneerelectronics.com/PUSA/Car/Amplifiers/GM+Digital+Series/GM-D8604 Let's root for each other & watch each other grow.
