SCV3000D running 3 X-12's?

Recommended Posts

Only problem is, is that you would be starving them for power. 3 dual 4 ohm subs can only be wired to 2.67 and 6 ohms. You will barely have enough power for 1 sub let alone 3. An scv3k runs 1500 at 2 ohms and you would be just over that, then throw some rise in there and yeah. Somewhere between 1k-1.5k give or take. I was going to be running a very similar setup, 3 x 12's with a same sized alt and 4 xs power xp3k's. Debating on Dual 1 ohms to wire to .67 or Dual 2's to run at 1.34. I think thinking of staying on the safe side since to power them suffieciently I don't think a 280a alt can do 4k-6k watts at below 1 ohm. So I am in the search of an amp or amps to get me at least 5k near 2 ohm.

fuck the plating. look at what the main metal used is. you could buy unicorn blood plated terminals but if its just covering up dog shit, whats the point

I'll admit, half way through sanding that fiberglass in the rain and cold while I was all itchy I was definitely starting to question why i was doing this haha

And .67 ohms. You forgot to math before you spoke.

Isn't series/parallel the way to get the lowest with dual 4's? Which would be 2.67. I didn't do math, used a website, cry more or be butthurt somewhere else.

No cry, no butthurt here !

Do it OP, if you have enough battery power. You have a good alt, you may need 2 big AGM : one upfront and one in the back, at least.

(That is the amplifier I want to run on my Zcon 15.)

Ive already got a XS power battery and have the Big 4 with 1/0 wire, so I think it can take it.

You should have no problem then running that. Those subs will be begging for more though. How did everyone figure out that .66. I have only ever used 12volt and could never find anything I would understand for formulas to figure out how to do what ever configuration I wanted.

.66 is parallel coils and subs. a full parallel circuit, not series parallel. You add the reciprocal of each voice coil (1 divided by 4) and then get the reciprocal of the sum. so:

y equals the voice coil resistance, and x is the sum. you have y, so you need to solve for x, and then find the reciprocal of the sum

1/ [x = (1/y + 1/y + 1/y+ 1/y + 1/y+ 1/y)] is equal to 1/ [x = (1.5)] so the reciprocal (1/x) of 1.5 is .66.

That's how you find parallel resistance of a circuit.

now the short easy way for subwoofers since it is assumed that all voice coils of a subwoofer are equal:

you have 3 subwoofers with two coils each, that are four ohm. SO, 2x3=6 coils. 4ohms divided by 6 coils equals .66ohm
