    Icon32 How to wire a capacitor correctly

    I recently purchased new subwoofers. This is my second set and I am not sure what size capacitor i need or how i wire it up. I have two 12" Kicker L7's with a 3000.1 Powerbass amp.

    Re: How to wire a capacitor correctly

    my ideas are an alternator upgrade, dual batt or capacitor. seeing as everyone has said the capacitor is not worth it what should i do?

    one wire connects to the floor of the dumpster and the other one goes up the salesmans butt who sold it to you and told you that it was needed.

    Definitely no capacitor, have you done the big 3 yet? Do that first and see where your voltage is sitting at.

    My voltage is currently at 14.3 how much should this affect it in the long run?

    Also have you installed them yet? How low is your voltage dropping? What kind of car do you have? Do you know how many amps your stock alt is pushing? A lot of cars don't need a H/O alt for 1500rms but much past it you do. I'd say get a bigger battery and big 3 first, it's best to match batteries if you're getting a 2nd one.

    14.3 on full tilt (as loud as it'll go without blowing tuned right) ?

    If so then don't worry about anything that's just fine IMO

    I just installed them today to check everything and make sure it was in working order. it works fine. Not too sure how low my voltage is dropping while in use though. i have a 95 silverado, but i have off-road lights and a train horn hooked up on it (not sure if this affects it much). i will check on my stock amp output soon. i just bought a brand new battery 2 months ago, not sure what size either. tomorrow i will get up and list everything.

    Check how low it's dropping while in use and also check again with the lights on. Really doesn't make a difference unless you plan on having your system on with your lights and train horn all at the same time.

    Like I said you shouldn't need it too many upgrades to push 1500rms, I'd start with the big 3 cause it's the cheapest/easiest

    Re: How to wire a capacitor correctly

    wow! 14.3 with 1500 watts is nice. i drop to 12's with the big 3 done in 1/0 and i'm only running 800 watts on the subs and around 800 on mids and tweets (mids and tweet amps are turned WAY down though). just goes to show how inefficient class a/b amps can be. (RF 801S)
