2014 SGS been running a tm400x4 for years and also heated gear (jacket and maybe gloves when needed). I’m adding a tm400x2 and want to make sure on those colder days my charging system will keep up.
Rockford says the x4 pulls 28amps and x2 pulls 23amps.
Heated gear is 7a for jacket and 2.2a for gloves.
I assume the amps will push their amp rating when pushed to the limit, but I’m not for sure.
Am am I safe or should I start looking at an upgrade?
Stock charging system will have plenty of output at 50 amps to run you heated gear and 2 of the RF 400/4 amps.
I am currently running a JL XD600/6 and a JL HD600/4 and have no issues.
The only thing you may want to consider is upgrading/replacing the OEM battery.
