I was just wondering I'm running 2 Amps and I noticed that when I put my system up high at night my lights begins to flicker a bit. Someone told me that I should go buy a cap and that will take care of the massive power drain.

Does anyone agree??

Is it like an extra batterie? I'm not sure how it works. Does it conect only to one amp or both?

A snip from a previous EF MAX reply on caps

SNIP>>CAPS: Do you need one? Very subjective subject. Basically a cap is like a reserve of electrical energy, "almost like a battery" On some systems when a deep bass note is played, the battery can not delivery enough electrical energy to the amp, this cause the bass to be delivered with less than its optimum ability. What the cap does is act as a reserve supply that can be called upon as and when needed.

A battery can not respond quick enough to the instant demands some bass system put on them and this is where the cap helps out because it can respond and recharge much faster than a battery.

There are some people who claim that a cap also helps in clearing up some of the middle and upper frequencies in a multi amp set up.

Before I went over to Digital class D amps I had a 5ch Genesis amp and their big Monobloc amp running my system [www.efmax.c.uk/serv01.htm]I had one Optima battery upfront and a second audio battery for each amp. BUT no cap. Considering this system could drop some REAL bass and that, that Monobloc at full tilt could draw more current than my alternater could put out, there was still no light dimming or degradation in bass output.

The key here is the power supply. Good and correct cable, I used two runs of 4AWG cable, fused at each end, to the batteries. Decent alternator and the consideration of a second battery.

I am not a great lover of caps but they do help some people out. It is worth noting that the better the amp the less need there is for caps. Often I see caps on systems that have very good branded amps, but their owners have been seduced by marketing bullshit.

As for fitting them. Safety is a real key issue here. Done wrong and this things can seriously harm both you and your car.

They should be mounted as close to the amps as possible. They should be earthed well and if possible to the same point as the earth on the amp/s. You need to take the power supply from the battery to the +ve side of the cap, then take a power feed from here to the +ve input on your amp.

SAFETY.. can't stress it enough, these things if shorted out can torch your car as if you set fire to it and poured petrol over it.. SAFETY...

Hope this helps... EF MAX

Well what should I do

I read your post and I understand what you mean. I'm running a 600wat pioneer aMp and a 255 watt Kenwood amp and I notice only when the car is parked that the light will flicker a bite when the bass hits hard.

What should I do?? Just leave it??


Thanks

On the assumption that you have good and correct size cable and earth to your amps and the alternator and battery are in good condition, a cap "might" help. A 2nd battery "might" help but you don't seem to have enough real wrms power to be having anything to worry about.

At the end of the day if all of the above are okay then the cap or battery might be your only choices but do check that cable stuff first.

forget the cap

a cap is just meant to relief some of the pressure off the battery... its not going to do any good if they battery sucks!!!

Get an optima red top battery, its about the same price of a cap retail.. these battaries are designed for the drain-charge- drain-charge scenario with a system...

but keep in mind that electricity flows the path of least resistance, in this case when an amplifier is wanting power, the pathway to it is Least resistant, so the real problem is the fact that in a car you dont have the power to begin with, so your goal is to try to accertain what power you have and to keep it effecient... some ppl believe in caps... some think adding battaries helps... nope they both just increase the load on the alternator whom is the true enemy!!! .. get a battary, then get a cap ....

OPTIMA batteries are good but the RED top is for starting the car and does not like repeated draining. For audio use, use the YELLOW top which is designed for the drain-charge- drain-charge scenario with a system...

Assuming that your MX6 is the same as mine, 93/V6 or similar, then I assume that you have the same alternator and if so and it is working fine, then it is more than enough to do what you are asking.

As for the 2nd battery issue, it is a must if you are going to be running a high power system as when the engine is running the main electrical load is dealt with by the alternator, but on heavy demands the 2nd battery behaves like a cap so to speak and also is helpful when you are playing the system when the engine is not running.

I have two audio batteries in the trunk of my MX6, very close to each amp and they work perfectly on the stock alternator.

I always have at least 12.5v when the system is on and the engine running and the difference in performance over having just one good battrery is amazing.

My amps push a TRUE 1x 1650wrms @ 1ohm + 4x55wrms @ 4ohms + 1x 325wrms @ 2ohms and I drive with main lights on all the time 24/7 and use the A/C a lot and I NEVER have any problems with lights dimming or degradation of bass quality or output.

Have a peak at www.efmax.co.uk/amg_mx6.htm there is a good break down of my set-up and how things have been set-up and put tgether..

Ok thanks EF MAX

I think I'm going to leave the Amp setup they way they are becasue like you said I'm not pulling to much Watts out anyways. Why should I spend $150.00 for a cap?? I will buy a new batterie when it go's on my car.

Thanks EF MAX You helped me out again!!

exactly that... you want a red top, it was designed for the dailey driver...yellow tops dont perform good under day to day situations, cold starts ect. .... if you do one battery under the hood, you should get a red!!!!, if you add battaries then get yellow!!!

Virtually no mater what you do your headlights are going to pulse with the beat. When your car is stoped/idling at the traffic lights the alternator is only outputting minimal current {amps} leaving the system short of power.
But a big battery is going a long way to fixing/helping the problem!

mr. mx6 has a good point! i got my alternator respun, have 2 1.5 fared fosgate caps hooked up to 2 fosgate power 800s. and it still faded the power. after i hooked the dry cll you saw a big difference!!

Caps for ACIDBURN

ACIDBURN,

I dont hink you are running enough power to require a CAP for your car I run more power then that and do not need one.
However I am a car audio installer and specialist I live in Markham if you want me to take a look at your system I would be more then happy and if you do need anything I can get you a GOOD deal on it.:cool:

Hey Cool !!!

Where are you Located and what's the Stores name? I've decided that I will forget the cap but I'm looking to buy a deck now. Would you be able to get me a good deal on a deck?

Msg with any information!
