Ok ,i got the capacitor QX series 1.0 farad Phoenix gold.I hooked it up, before that i charged it .I'm not sure if i did it right, can you guys help me out.

thanks

 

That's what you are supposed to do. Does it have a problem or something?

 

the light still dims when the bass hits hard, so what happened? do i have to fix the problem using an alternator or capacitor? or can the problem be fixed some other way?

 

how did you wire the cap? how much current does u'r amp draw? 1 farad might not be enough. i have an alpine 1507 and had 1 cap. the lights dimmed slightly. so i added another cap and seem to do the trick. if you have the $$$ i'd got with a new altinator.

 

Yes, it is a good idea first to make sure the cap was correctly wired in parallel (+ to +, - to -)...a cap in series is an interesting thing to see indeed.

"the light still dims when the bass hits hard, so what happened? do i have to fix the problem using an alternator or capacitor? or can the problem be fixed some other way?"

If the lights still dim you are still seeing a voltage drop as a result of peak pull...so you need to make sure your current draw is less than your alternator output, including the car electronics...you could use a little multimeter, or just check with your manufacturer as to the peak draw of your amps...if you have less draw than input, then you're ok and just need another cap or two wired in parallel...my favorites are the 1.5F Lightning Audio Digital Storms...always work for me. Otherwise you'll be looking at an alternator upgrade (see my other post).

yo hiep i have the same head unit as u and a ppi amp to poer my 12. i am running the full range speakers off my radio which i bet u are doing that also. Alpine 7875 are very powerful heads and do not required external amps to get loud.with my premier speakers i can turn the volume 20/35 and it will give me a headache. that a lil over halfway. my light dim slightly also at this level. I have the 1 fard cap on my small ppi amp so i dont think its the amp pulling that much power. what i think is that its the radio pulling the power b/c we are running speakers off of it. It does make sense to nme since wehave the built-in 60x4V-Drive ampis in our head unit. So what ever u do to take care of the dimming let me know. For the time being this iswhat i concluded. Hope this helps

 

Did you make sure you did in fact wire up the cap properly? I've attached my system diagram so you could see how I wired mine. If in fact your lights are still dimming, you may need an alternator upgrade (you can check to make sure if you have a multimeter). If your system, with the ignition system and other car electronics, pulls near or at the max of the alternator, then yeah upgrade it. That is what I am doing, and I have a groupbuy going.

www.phoenixgold.comTi/Cap. I changed my cap Ti series 1.0 with digital and led monitor . This cap is work great and now my light is dim less.

 

 

a cap wired in series might not even work at all...

a cap wired in series with an impedance load will imitate on open circuit right after DC steady state... the result will be little to no current

make sure its wired in parallel and keep the ground wires as short as possible. charging??? it shouldn't even take a second.

That's true...but it's not just a strict impedance load...it's a variable impedance load...but unfortunately this forum doesn't like ascii...I can make a drawing later...
