    2 subs without alternator upgrade?

    im very lost on what subwoofers i want. i want two 12s and i was going to go with the jl w6 but everyone has told me to go with sundown. only problem is someone told me i would have to change my alternator and wiring if i wanted to push two sundown SA12, which makes since but i dont want to have to do that..anyone have advice on 2 subwoofers with a little bit of both SQ and SPL and not have to change the alternator

    Subs have nothing to do with needing electrical.

    Your electrical draw will determine your electrical need, not which subs you choose.

    Re: 2 subs without alternator upgrade?

    I'm most likely the guy who told you that you need an alternator in your other thread. If you were to run a true 2,000 watts, you will suffer severe voltage drop which does not make amps very happy. I mean, make sure to get a good AGM battery under the hood and do the Big 3 (don't connect to engine block. Connect to alternator case, fyi).

    Take my advice for what it's worth. I cut my teeth in car audio back in 1998, when lower powered, higher efficiency setups were the norm. I was hammering off of a bridged 2 channel Phoenix Gold amp making only 300 watts. It's all in the install. I've since gotten with the times to some extent. However, it's common that someone here would love the fact that a sub can TAKE over 1500 watts of power, but I would be very sad that a sub would NEED that much power to shine. I would be even more sad that said system would require me to come off an additional $400 so it could all run properly and safely. It's all personal preference.



    Simple SQ System:

    Head Unit: Alpine CDA-117
    Active Crossover: Cache' CEX
    Front Stage Amp: Boston Acoustics GTA-704
    Components: Polk Audio DB 6501
    Sub Amp: Boston Acoustics GTA-1000m
    Sub: JBL P1224, 2.5 ft^3 @ 25 hz enclosure
    Rear Fill: Sony Xplod 5.25s on HU power lolz

    Re: 2 subs without alternator upgrade?

    no you shouldn't have to change anything ,you will have to do the big 3 tho.maybe a better battery down the road ,but 1200 watts rms is not that bad on your stock electrical unless its a crappy amp.

    As said most electrical systems will support 1200 watts with a Class D amp, a good battery, and the big 3. But even with that depending on the vehicle running true 1200 watts RMS will be hard on a stock electrical system. If you have the space you don't need a lot of power to get loud. I am a big believer in efficiency and I don't like running high power beating the hell out of my alternator.

    A lot of people around here say they have a 1200, 1800, 2000 watt or whatever amp when it's really only 500 RMS. May be the same case with your buddy.
