3 dual 4 ohm subs, any wiring configurations? (hoping to use for 2000@2ohm amp)

[WOT]

Trying to think of some ideas for a setup and cant find any info on wiring 3 Dual 4 ohm coils.

Was thinking of running 3 audioque sdc 2.5's off of 2 cadence txa 1000D's, which when the amps are strapped together make 2000rms @ 2ohm.

Was looking at 3 subs because I currently have 2 and want to make a wall, but may not have enough space to give 4 subs the room to breath.

Was hoping there might be some way to make this work.

Thanks guys

.67 Parallel-Parallel

2.67 Series-parallel

i think thats right

Im not much for tech talk on wiring, can you explain what that means and what kinda power Id be putting to heach sub?

So there is a way to wire it? Still looking for diagrams.

Thanks alot~

All subs + to + then - to - then a wire from one + on one vc and - on the other On each sub and wired to together at the amp=.67

All subs one voice coil + to one vc - then the remaining terminals go to the amp all wired together = 2.67 I know it sounds confusing but its just like wiring for two of them, just one more

Check out rockfords site.

You need to run at 2.67 so you dont pop the amps

Im trying to get that diagram but RF is slow

After imp rise your gonna be seeing almost 3 ohms and those amps wont be putting the 2000w. Just do 4 subs, im sure you can fit 4 in a wall.

Ok so I get that 2.67ohm load, would that mean I do 2000/2.67 which is 750ish. Is that how much each sub would be getting?

Why would they not be doing 2000rms? thats what there rated for at 13.8volts and Ive got over 14 when driving.

Just curious if that would work or not... wiring them the way the rockforad website shows anyways.....

Id go with 4, if I had more room. 3 gives me plenty of room to get LOUD!

It wont get the full 2000 watts cuz when an amp sees a higher impediance it wont put as much power out, Your amp is rated at 2000 @ 2 ohms but prolly like 1000 @ 4 ohms. The lower the ohm load the amp sees the more power it will try and push. But not all amps go really low so you dont want to make it a really low ohm rating, it will destroy your amp if you give it a lower rating than its rated for.

oh, so how exactly would I be able to tell what each sub would be getting after imp rise and a 2.67 ohm load?

Well as long as all the subs are the same ohms, It should split it out evenly for each sub. Now i am not sure what your amp will put out at the ohm rating you give it, So someone else will have to help with that.

wish i had the god****ed room for 4 of them!

Well without having the subs, amps, and a multi meter, there is no way to know exactly but you can estimate. Your amps strapped will do 2000rms at 2ohms on 13.8v and 1300rms at 4ohms on 13.8v so i guess 1700rms at 3ohms on 13.8v. So around 560 watts each sub. Now take into account voltage drops to

alright cool thanks guys, definetely not even worth it to run 3 then, just gonna have to see if I can figure out something to get teh room for 4 or just keep the simple 2 i have now

Cone area is more effective than more power.

more expensive and time consuming in this case to lol
