I searched and could find nothing.

Planning an audio system for my bike (2010 FXDC), and need to know how much RMS power my charging system will support, as well as any tips or tricks to getting more out of it.

All lighting has been converted to LED.

Still has the 35A factory charging system. Willing to swap to a 55A system if necessary. I couldn't find anyone that makes custom Harley charging systems. If possible, I'd just get one with plenty of extra room and not worry about it, but it seems like a lot of work and expense to go from 35A to 55A.

 

Okay so we're talking a Dyna glide? What did you have in mind? No bags or fairing on that bad boy.

 

My dyna, hehe:

 

Now I can put a killer sound system on that one!!

 

maybe a 1 farad cap just as insurance???

Caps are bad. Especially on a bike. Never run a cap on a bike.

 

Never!!

 

Could you please elaborate?
Thanks in advance.

 

capacitors are a fact of life, machine already has them, electronics can not survive without them.
your stock 35a system has a max rms output of 315 watts ac with 12.8vdc input source
a 50a system will have 450 watts ac with 12.8vdc input

stock 35a dc is 448 watts dc the 50a dc is 640 watts dc

roughly ac is 3/4 of dc watts.
is what it is, no way to boost it.

 

Always that guy who wants me to get technical. I like to keep it simple. I leave all the technical jargon to Slye and Haze. . .LOL But since you asked me. Capacitors don't produce any current. they are basically a "buffer" between all your devices that do produce power, i.e., Amp and Stator. Your stator is already working overtime to pump juice to the battery while your system is playing. Why would you want to ADD a device that produces no power? Just one more thing to drag your system down IMO.

Realistically where do you think the power comes from to charge the cap? If you guessed the stator/alternator you would be right! If you're charging the cap, you're taking power AWAY from the amp. That's about as simple as I can explain it in layman's terms.

You're better off adding a deep cycle battery to your system.
