Amp Terminals?!? Help

[Stem 10+ year member]

Hey fellas,

I was recently going to purchase a Power Acoustik A3000DB to power my 2 12" DC Level 4 (1000wrms, 2000peak). Now I was going to wire them both to 1 ohm, then theyd be receiving about 1150w each. Then i realized through wiring configs that you cant wire 2 12" subs to 1 ohm. So THEN i figured, alright i guess i can just wire them separately to 1 ohm each because most amps come with 2 sets of terminals. THEEEEN i found out the PA A3000DB only has 1 terminal.

SOOOO, now i need help, is there any possible way to wire the 2 subs to get a 1 ohm load, OR get the 1150w each, WITHOUT a clipped signal.

If not, is there any amps that have 2 terminals that can throw out about 2400w at 1 ohm, for $300? Thanks guys i know you'll help me out.

no you cannot wire them to 1 ohm anyway together.

Yes, you can sometimes wire 2 subs to a 1-ohm load... it depends on the sub. It depends on if they are Single Voice Coil or Dual Voice Coil, and the impedance of each coil. If you have (2) dual-4-ohm subs, then yes, you can achieve a final impedance of 1 ohm.

Lots of amps will give that kind of power. You don't need two sets of output terminals on the amp, either, you can wire both subs into one set of terminals. Many mono amps have two sets of terminals that are merely internally paralleled.

If you researched DC Level 4 subs, you would discover they are dual 2 ohm woofers. His options are 0.5 ohms, 2 ohms, or 8 ohms.

Sorry, no I didn't feel like researching his subs.

Next time maybe I will... but doubtful.

So from what you are saying can i wire each sub separately to 1 ohm, then wire both sets of wires into one terminal?

Also, [the PA3000DB puts out 2300w @ 1ohm] if i wire the subs down to .5ohm load, how would i be sure the amp is putting out enough/too much watts? If i were to just use the Sqrt(power x resistance) = Voltage equation to find out how many volts to tune the amp too, would that ensure the amp is putting out the necessary power? Thanks guys

You should only wire to 0.5 ohms if the amp is 0.5ohm stable. Very few amps are. If you have 2 terminals and you wire both to 1 ohm and then put them together, you have just made 0.5ohms. There is NO way to wire these subs to a single amplifier at 1ohm. At all.

Will any bad happen if i wire them to .5ohm to the amplifier? What would happen? If i did what i was talking about before, (finding out correct voltage, then set the amp to that much power) with it at .5 ohm would it be ok?

u will clip ur amp and prob blow that cheap pos up, get an amp that will do 2 ohms or 1/2 ohm with the power u want, prob wanna find something 2ohms more popular and price will prob be more practical

$20 your electrical system isnt up to par for .5

Or go buy (2) 4ohm DVC subs.

 

[Stem 10+ year member]

they dont make them in 4ohm dvc. so i'll have to find a .5ohm stable amp? anyone know of an amp that puts out 2400-3000w at 2 ohms for about $300?

thanks for the help fellas

 

[Silverbane 10+ year member]

If I were you I would look at 2 cheaper 1-ohm stable amps and put one amp per woofer.

Something like a pair of these...

Not great but will do the trick for you.

 

[Silverbane 10+ year member]

Or try to find a used Crossfire VR2000D.

Have you asked them about this? Many of the smaller companies will custom make woofers if you are willing to wait a touch longer for them.
