hi, forgive me if this post has been repeated.
but i couldnt search nothing, help would be great,thank you.

question is

could one farad capacitor connect to an subwoofer mono amplifer and a multi channel amplifer together? or does it need another farad for other amplifer?

 

One capacitor installed the way you intend will work fine.

Simply connect the capacitor and amps through a distribution block. Some of the more involved car audio forums question the usefulness of capacitors at all, but most people(me included) still use them. If you are concerned about voltage issues, be sure to do the big 3 upgrade first.

 

The capacitor should be wired in-line on the main power wire from the battery. From the cap, the main line would continue to some sort of distribution block, which would then branch the power wire out to the amplifiers.
The whole point of capacitor usage in a car audio system is to supply a quick charge of additional current to the amplifiers when needed. Capacitors store current like a battery, but can discharge at a much higher rate. Unfortunately, they are NOT an adequate replacement for a larger (higher amp) battery. If you are concerned about the current draw from your audio system and you are experiencing the tell-tale signs of current starvation, i.e. lights dramatically dimming to the hits of the subs, idle issues as current draws, etc., then you may want to consider spending that capacitor money on a larger battery instead. If you're just looking to add a little more support to the amplifiers, then by all means, a capacitor will do nicely.

 

thank you for replies,

but i still dont know, say if one mono amplifer rated ( 300 watts ) and multi channel amplifier rated ( 1000 watts) both connect to 4 farad capacitior, would that work well or they will break?

 

It would work fine. A capacitor is not going to damage your amplifiers and vice versa. The worst thing that could happen (barring any physical failures or improper installation problems) is that the stereo system would draw more current than the capacitor could deliver which would starve the charging system just as if the capacitor were not installed. In that case, you would need to get a larger battery, higher output alternator, or both. Based on the specs given, unless the amplifiers draw massive amounts of current by some electronic freak of nature, I doubt you will have any issue whatsoever.

 

thank you, so i can do this set up? sorry im new at this.

battery> fuse holder> 8 gauge power cable> 4 farad capacitor> 300 watt amplifier and 1000 watt amplifier.

 

I would recommend using a minimum of 4 gauge wire rather than the 8 gauge, preferably high quality wire with a high thread count... Lightning Audio, Stinger, Tsunami, etc..
Higher thread count = Less resistance = more power to the source = steady, more reliable output
Be sure you use the same gauge (and quality) wire for your ground that you do for power.
You can use 8 gauge wire from a distribution block to the two amplifiers, but I would keep those stretches of wire as short as possible. You can also use a ground distribution block to combine the two amplifier grounds back to one larger gauge ground wire. Again, keep the amplifiers' ground wires as short as possible. This will help keep things organized and eliminate the introduction of noise through ground loop. The shorter the ground wires, the less likely they are to introduce noise by coming too close in proximity with signal (RCAs) or other important components.
Keep your power and ground wires as far away from your signal (RCAs) as possible. This will also help to keep out unwanted noise.
Above all, make sure your ground connection is as close to frame as possible and is free of any debris and paint. You will want to grind and/or sand the ground point to remove any and all dirt, oil, and paint so that the ground point is as bare metal as possible. The rest of the electronics in the car ultimately use the frame as a ground, so using a ground point as close to the frame as possible will also help to eliminate the induction of noise via ground loop.
Good luck, and if you have any questions, feel free to ask.
