After having my bike flashed with the pbr300x2 and Polk mm651 I had to install the remote turn on wire to get the amp to turn on. Now when I start up the bike I get a pop from the speakers when firing up. Is there a way to eliminate this or have I done something wrong with the install?

 

its a common issue with some systems. You can live with it or add a delayed turn on module such as the PAC TR-4 should fix it.
