Ohm question on sub

[Repoman79]

What's the difference between 2ohm or 4 or 8 ohm subs with the same rms & peak power the reason I ask is because I'm liking to purchase some 12s and they all have the same rms & watts but with different ohms

Match the ohms to your amp. If your amp can do 1 ohm get subs that can be wired to 1 ohm. 2 ohm? Get subs that wire to 2 ohm.

ok Ya cause the subs I'm looking to purchase hds312 d2 1200rms each so I'm thinking is 2 ohms and the amp is 2000rms @1ohm so I'll have to wire the subs to 1ohm correct

if you get 1 sub, ya you can wire a d2 sub to 1 ohm.

if your getting 2 subs get d4 subs.

what amp ??

the amp I haven't decided yet. And the subs they only have d2 no d4

they just dont have any in stock right now. but they do come in d4 .

are you doing 1 or 2 subs ?

. 2 subs

ok with 2 d2 subs you can go with .5 ohm or 8ohm.

or you could do 2 ohm total.

see were for wiring details..

so find an amp that will do around 2500 rms at 2ohm. but bigger is always better as it gives you head room and you do not have to set gain high. and thats a good thing.

or if you have the electrical get an amp stable at .5 ohms and wire to .5 .

but you need a h/o alt, a good under hood battery ( amg ) and 1 or 2 batterys in the back. all 1/0 wire with 1/0 wire for the big 3 .

in order to run at .5 ohms you need a strong electrical system to support it.

what type of electrical do you have ??

what size alt? what type and how many battery's ? big 3 done ??

use all 1/0 wire.

also dont skimp on the box, get one made for the subs.

Can I just get an amp that's 2500 @2ohm or 8

That type of power at 2ohm isn't cheap.

What u mean lol

It's a lot cheaper to buy an amp that does 2500 at 1ohm rather than 2.

He means it's more expensive to find a amp that does 2500@2ohm vs 2500@1ohm

2500 at 8ohm lololol. Good luck with that.

Could do a big Alpine for 2ohm.

i found an Lanzar VIBE442N 4 Channel 2 x 2500 Watts Max @ 4 Ohms Bridged would this amp work for 2 hds312 1200rms 2400w peak power @2ohm
