  1. in my opinion when youre running a long RCA I prefer to purchase more expensive RCA's because they are twisted together and have extra extra insulation on them to keep a clean signal. All the power wires in a car can cause alternator wine and bring unwanted signal into the music with cheap RCAs, so I get monster RCAs. Also nice RCA's will atttach onto your equipment better. I know some people tape their RCA's, but if you buy good ones they wont come off.

    Just my 2 cents

  2. Guess if you would have said to give more control to the driver ... it would have made more scence to me. Thats why I had a Paremetric EQ om my system all those years ...

    but to boost headunit voltage ... is something I would not do ... gives a great reason to have a DD1 distortion detector ...

    theres gonna be alot of it ... My suggestion would be to buy a adequate head unit to do the job correctly ...

    Why would anyone want to amplify bad voltage ??? I do not understand this at all ...

    Give me a clean 4 volts anyday !!! If that doesn't fit your needs, Your amplifier is not strong enough to do its job anyways ...

    Pretty much what cableguy says. I used to have a line driver until I plugged the dd-1 to it, literally any gain past 1/8 of the way up was a distorted signal. Needless to say I got rid of my eq and just use my hu, but I am in the market looking for a bass processor

  3. well i need to rebuild the box and add more port, but i havent gotten around to doing it.

    but right now as it stands:

    system isnt dd1 tuned, but tuned by ear with a 35hz -6db tone, and probably is way under the max this amp can push out.

    head unit is +5/15 on the subwoofer out position (4v preouts)

    head unit is 32/35 on the volume

    voltage drop is about 12.8-13.8 depending on the song and how long im full tilting.

    in general, they are still VERY stiff and i'm still not xmaxing them.

    sound wise is perfect for me, i dont have a sq setup by any means, but these subs transition quite nicely from 55hz to 28hz. (in THIS box)

    i only have about 10.9 square inches of port per cube so im kind of choking them if i go even 1hz under the tuning of my box (32hz tuned)

    31hz and under i can smell coil after about 10-15 seconds.

    i'm 100% confident about my setup as it stands, even with 12.8v drop.

    as long as the song is clean, box is right, and amp tuned properly you will be 100% fine with 1500w.

    now with like 2200W or more, you'd have to watch the voltage and watch for coil smell or shit can get messed up quickly. playing below tuning is also a bad thing.

    you're actually really over thinking this, a 1500W amp on two SA-12s is a joke to these subs

    you think youre around 145db?

  4. Came across what looks to be some good priced welding cable...does this seem like a good substitute for 0 gauge?

    Welding cable is great stuff as long as its ofc. its gonna be a little less flexible but still I'd use it.

    If youre short on cash get knukonceptz CCA 50ft spool for less than 100. Its cheaper than welding cable

    Wouldn't the OFC welding cable be better than CCA?

    If they are the same size, yes.

    Copper is about 1.5 times as conductive as aluminum

    So OFC figure OFC is around 1.4 times as conductive as CCA

    But, consider that KNU is oversized.

    According to the AWG spec, KNU 1/0 has a .45 inch conductor diameter, which puts it at just below 4/0 wire

    I will round down to 3/0 for this though

    1/0 has 53.5sqmm of cross sectional area, and 3/0 has 85.0sqmm of area.

    This gives the KNU KCA wire around 55% more area than 1/0.

    ~50% more surface area, ~50% less conductive. So KNU KCA should be just as conductive as OFC welding cable.

    You decide if you want to deal with trying to fit 3/0 in 1/0 terminals. There should be no difference between the conductivity of KNU CCA and OFC welding cable.

    yeah thats true, I used 2/0 lugs to fit my knu in there. The only thing I don't like about the cca is it does get hotter than OFC which means there's resistance, but technically it should be the same resistance so????
