anyone here on the forums using a jl10w7 that are experiencing light dimming

Does it dim with your car on? if so, You might want to invest on a capacitor. Your battery can't handle the power getting drawn by the amplifier. Just curious, What amp are you running?

symalik

that all depends on what amp you use, and how much current it draws. Really has nothing to do with what sub it is. Sure the sub might make the amp draw more current but the amp is the one that needs adjusting or capacitor or whatever

im using the jl 500/1 amp

Set your gains lower, if you want more bass, you have to add a capacitor to minimize the dimming problem. Are you running any other amps? or just one?

just one

YOU NEED A CAPACITOR. Im running 300 & 500v1 and a 10w6 with a 2farad cap.

im thinking of getting a yellow top optima

You need a capacitor,Even if you upgrade your battery. And if you upgrade your battery, Stinger batteries are alot better if not, kinetic batts are good too

just wondering if i might have the same problem too, i am going to hook up a a cerwin vega EXL-350 (350 amps) and a single jl audio 10w3v3, do you all think i will need a cap as well?

The g37 has a pretty beefy standard alternator (150A.) I wouldn't bother with a cap they're just a band aid.

First step upgrade your grounds

Next you could always upgrade the Alt. What guage wire you using on your amp?

I hear upgrading the Alt can be a bad thing. I have been told that it can mess with other parts of the car since it will produce more power than needed. I remember hearing this back in the day when my friend did this on his car and it messed up some of his electronics on the car. Not sure if this is true for all cars and for new cars like ours. Caps are the way I would go.

caps are a band aid. Just think about how much power a capacitor can hold generally you're talking 1-2 farads. The power discharges very quickly.

So what happens when this power discharges - it needs to charge back up again - how? - by drawing current. So now you have your amp that's pulling current and the cap pulling the current to recharge itself. In the long run it is much harder on your system.

Think of a strobe light, it strobes with the help of a capacitor. It flashes and depletes the light stops to recharge the cap and then the light flashes again etc...

Maybe a small 2nd battery in your trunk? My lights do not dim at all and I am running a considerable amount more power

bboysteele

I know the second battery is a good idea if you are running alot of power. As far as the Cap though, they are good too. If your lights are dimming on those hard hits then the cap can be used to even out the system. It is like a UPS sorta were the amp takes the power from the cap when there is not enough from the Alt/battery. It evens out the power. Works on a lot of systems that I have seen. Like anything else you will need to replace the cap down the road though.

I plan to use 8 guage if you are asking me.
