    Alright I used to have 2 10's with a 1000watt peak amp and they ran just fine (dimmed the lights but was fixed with a new battery). But I just got 2 15's powered by a new 1800 Watt amp and my lights dim and if i turn it up the amp will go for a few and shut it self off. could this be caused by a voltage drop? I.E. if I got a capacitor would it help?


    my wiring is all fine, and my battery is great, the yellow top optima(SP?).

    capacitor will make it worse. Caps drain almost instantly, and then they are a burden on the electrical system which will have difficulty running the amp AND charging the cap.

    Yellow tops are designed for long-drain applications... I wouldn't use one as a starting battery.


    To test for voltage drop, use a voltmeter and a test-cd to run a single tone and measure the voltage at increasing volume.

    Yellow tops work just fine for starter batteries. Infact, they have more rated CA than most cheapo conventional batteries that start your car just fine.


    As for a cap, as jollygre said, it wont help unless you already have the electrical system to support your stereo. They are ment for instantanious draws to keep voltage flat with dynamic music, they do nothing but suck up extra current which is bad with long, drawn out beats.

    if it's a true 1800 watts, add a 2nd battery..but first get a good shop or installer, to make sure the proper 14 volts is getting to the amps.

    Then how should I go about fixing the dimming of lights?

    Maybe a new alternator, I'm using the stock one currently and im sure it is a piece of shit.

    how many amps is your current alt. rated at?

    Proper 14v? Not all chargeing systems are designed to run at 14v. Some are 13.8, 13.5, 14.4, some go as high as 15.

    Yay for me:wiggle:

    I just wanted to make sure that would be a possible problem.

    Just upgrade your Big 3 wires to 1/0 gauge. IIRC, the three wires are alt to battery, chassis to battery and engine to chassis. CB will know for sure, so correct me if wrong.

    Id go with alternator, 160 amp would be bad ass for you.

    the noobish is strong in this thread......go see a quality installer and let them get you set up with alt, and upgraded wiring.

    question: what percentage of total rated amps should an alt be doing at idle?

    What he said.

    That will help with dimming. It wont make up for amperes you dont have though. Upgrade your wiring, if you still have too much dimming for you likings a HO alt is the best way to go.:)

    Exactly. It's kind of like having a swimming pool filled with water, with a 4" outlet to drain it. If you put in a 16" outlet, you don't have any more water, but you can help it flow and be more efficient.

    What amp do you have? I only ask because if you truly had a real 1800watt amplifier, you wouldn't be asking us if a capacitor would help your problems.
