32Blew Posted July 17, 2019 Report Share Posted July 17, 2019 Good day all, I used my DD-1 to tune my amps in my 2003 Monte Carlo SS, car got totaled, so I bought another one, same exact car. I took my beat out of the first one, and re-installed it in the new one, no problems. Fast forward a year later, another young driver hit me, DAMN IT, second Monte totaled. This time I bought a 2007 SS. I have installed all my gear, except my Odyssey battery, as it won't fit. I recently burned up my factory alt. and had to buy a HO alt. My question is, do I have to re-tune my amps? I know the amps were tuned to the voltage of the head unit, but is the voltage the same in the new car? An '03 has a different OBDII protocol than an '07, the '07 is CAN BUS, the '03 is not, and now no factory alt, does a cars voltage affect the voltage of the head unit? Thanks.

reedal Posted July 18, 2019 Report Share Posted July 18, 2019 It takes no time at all to set gains with DD-1. Just do it anyways, just for peace of mind to know you are correctly set up in a new vehicle.
