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

I am running a Mechman 220 on my 2007 Honda Civic. While the voltage does fluctuate due to the PCM controlled voltage, I usually see at least 14.0 volts. I have not encountered any problems with my current set-up, which draws maybe 150 amps at full tilt. I see around a .3 volt drop with only the starting battery. The real test will be the new install which will pull 450+ amps. The alt will be backed up by a couple of group 31's or more...

No, I would advise not to get a VCM or Step down module. ESPECIALLY, and I emphasize that, lol, that it's a 2014. Getting a higher output alternator that is pcm controlled to mate with your car is best thing to do, but, good luck finding a manufacturer for that. Your best bet is to go for efficiency. This means, use less power, bigger box. You are very limited by choosing that vehicle for spl.
