I am going to be running a Rockford Fosgate 501bd Mono Sub Amp. I am going to wire my sub for a 4-ohm load and the amp provides 300rms at this 4 ohm load. I also have a brand new 1 farad capacitor. My question is whether or not to install the capacitor. People have told me that it really helps and others have said that it will actually work the alternator even harder because it has to store power in the cap also. Any thoughts?

Thanks,
xr72z

With adequate wiring there is absolutely no need for the cap. Your not pulling that much power anyway. Ebay it to someone who thinks they need it!
Use 4 or 2 gauge wire, and you'll be grinning.

Speaking from experience, run the cap. I was running without one for quite a while, with 4 guage wiring, and went through 4 alternators in about a year and a half. Put the cap on and haven't swapped the alternator since.

adequate wiring or not. still use it. your hits would be harder then when you wouldnt have had one in your system. and dont run anything less than 4 gauge to it. your wasting your time and money if you do run 8g or less to the cap.

its a rockford amp, they are supposed to be decent. its going to have lots of internal capactors, i don't think there is a need for it in this case. usually a farad is for 1000 watts isn't it?

i think i may not need a cap cause its only 300watts rms. but should wire it in? i was also told that by adding a cap u are adding more wiring terminals into the system thus causing electrons to travel through more things. i dunno my friend was giving me all this scientific mubo jumbo on why NOT to get a cap.

It's your call man, but when I didn't have a cap, and was going through alternators like crazy, I was running all rockford fosgate, and pushing no more than 300 watts out of my ENTIRE system. Just a little food for thought.

I am running almost 2000 watts, no caps, no problems. My last car was an '01 jetta with about 3k watts, no caps, no extra batteries, no problems. The car before that, a '97 neon with roughly 4500 watts, no cap, no extra batteries, no problems (except for dimming lights). I have only burnt up 1 alternator in the past 6 years, mainly due to crappy design (Chrysler), and I have never used an upgraded alternator. The key is having proper size wiring THROUGHOUT the system. Make sure you are using at least 4 ga. from the alt. to the batt., and I typically don't do anything smaller that 2 ga. from batt. to trunk. Upgrade all your grounds to the largest size you can afford, it is the biggest difference you can make. Last thing is to check for corrosion at all wire termination points. If you see corrosion, the wire should probably be replaced since corrosion will creep into the length of the wire.

so it seems as though the majority is sayin that with proper guage wiring and proper installation... a cap is not neccessary. all in favor? lol.

hey az... what do you mean by "Make sure you are using at least 4 ga. from the alt. to the batt., "?
