What 6.5 flash do I need to have the dealer do for a 2 channel RF PBR 2 CH amp and Hertz 6.5 coaxial speakers. Not really interested in doing the magic box after reading some the other posts, thanks for any input.

 

I used amp 1 and 2 off, 8 speakers with mine. YMMV. You might want to check in the Audio forum, but that has been a good solution for a lot of us.

 

Agreed.. Worked very well on my '14 SGS

 

Great, thanks !

 

i flashed for 4 spkrs amps off... it is kinda blah. maybe 8 is different, not sure. but i talked to Ed at Cycle Sounds and I know tech stuff and what he explained sold me on a box and stock flash. Plus I emailed from his website at 830pm on a sunday and he called me 20 min later. He personally guarantees satisfaction or money back. no one knows what the flashes exactly do because there is no factory documentation or support on the matter. Ed is an electronics engineer. I may rip out my PBRx2 and Polk MM651s and install them in my tahoe and buy Cycle Sounds amp and speakers yet. I want my sound quality and decibels

 

Theres a HUGE write up on this I did in the audio section, more information than you can shake a stick at
