Has anyone done A Big3 under the hood on a 2020 RLX SH-AWD for adding an amp & sub to the car? I’m trying to get the best idea of how to go about doing it. It’s a lot more complicated then when I did it on my 2005 Honda Accord many years ago. The cables are already a thicker gauge then you usually find on cars but they could still be a thicker gauge to help with lights dimming & what not. I’m thinking about adding my JL Audio HD750 amp to push a 8” JL Audio. W3 sub. I went with the 8” sub bc I was looking for that super tight bass that you don’t really get by going bigger then that.
