I have a 2014 Honda accord sedan that is in dire need of a serious audio upgrade. The issue i'm having is I can't seem to figure out how to upgrade the electrical to support the 3-4.5k watts I plan on running. The Alt only puts out 110A but the shops in my local area say its a "ballsy move" to upgrade it because the engine is only a 4 cylinder 2.0. Would getting a VCM and a step down module be my next option to support the amount of watts I plan on running? any advice helps! TY
