2 or 4 ohm?

[CJ_Clio89]

Right subs i want to buy come with either 2 or 4 ohm option whats the difference? whats better etc?

 

[Laura]

its the voice coils

one will be dual 2 ohms
the other dual 4 ohm

one puts a 2 ohm load on your amp the other puts a 4
dual 2 puts a 4ohm load on
dual 4 a 2 ohm load

it depends on your amp

 

[CJ_Clio89]

so what happens, if you buy the wrong ohm for the amp etc? does it blow it up....

 

[Laura]

yes if you buy a dual 4 and your amp is not 2 ohm stable it will die
if you buy a dual 2 and your amp is not powerfull enough it will sound poo

whats your amp and whats the sub

 

[CJ_Clio89]

Well what i was going to do to buy was 2x alpine type r subwoofers, to be honest haven't really looked at amps yet, but now i know what to look for....

So...if i had to choose the 2ohm or the 4 ohm to buy an amp for...what would you choose personally, or doesn't it really matter?

 

[Laura]

well amps are more powerful at 2ohms as there is less resistance

so an amp thats powerful at 2ohms and get subs at dual 4

but you will need powerful amps to run them

 

[CJ_Clio89]

Confusing abit isn't it, what make of amp should i be looking for, i know the alpine type r's are under rated so i can defintly push them hard, just need perfect amp...

Do i go for a powerful 2 channel or 2 class d monoblocks?

 

[Laura]

personally 2 monos

you got a link to the subs?

u using 12" or 10"?

or 15" lol

 

[CJ_Clio89]

Will have 2x 12"....rather nottake out my backseats for 2 x15" at the minute!

I think i will go for the 2 monoblock option...

[Laura]

2 of them would be good but maybe a little out of budget?

 

[CJ_Clio89]

i was just looking at those, i mean perhaps wouldnt be able to get them in one go, but thats definatly a pretty reasonable price.

What you have in your car ?

 

[Laura]

at the moment nothing lol

ive just got a new car and have just bought an RE SE10 V4 sub only a little 10" one running it off an alpine amp little more powerful than the one i suggested for you, DVD head unit and seperate 5 1/5 screen, not yet decided on the mids

had loads of different installs me, new one in each car

 

[CJ_Clio89]

Way to do it, try all sorts...at the minute what i have is ok, just desparately need to change the subs,

I have alpine type r components up the front powered by 1500watt loudest.com amp

I have 2x of the latest black sony subs 12" powered by one of the JBL GTO series.

I know everyone rips sonys, and in honesty its why i want to change they can't even compete with the component speakers honestly! I mean they sound ok , but its not a quality bass, if bass kicks are to close together it merges into one and doesn't sound to great to be honest. I just want something with abit of grunt and quite frankly something people won't look at on here and go ... ahh sonys gay! It was a good start but lol three months later ready to move on now !

 

[Laura]

well i did the stupidly loud install

the (bit of everything install)

and the SQ install

 

[CJ_Clio89]

That first one looks mint!... Be interested to see what you do in the future!

 

[Laura]

it was heavy big and made your head hurt lol

 

[CJ_Clio89]

Good lol its what you want, bass doesn't hurt your ears just your LUNGS!

 

[Laura]

its not what you want in a day to day car lol

esp when you cant use your boot for anything, my my 1.2 slower than well a 1.2

plus i was only really testing the equipment for vibe, which was good as they then released them lol

 

[Laura]

the subs also make a great tool holder, see bakground of pic lol

 

[Dink]

if you are going to get 2 subs then get the dual 2 ohm versions

then that way you wire each sub so it's 1 ohm and then wire then in series to show the amp 2 ohms

 

[CJ_Clio89]

Thanks mate, much appreciated.....

( PS, one hell of a toolholder actually ! )

 

[CJ_Clio89]

Just so in conclusion, correct me if i have read all this wrong,

For the best i could make it, i want a 2ohm amp with the 4 ohm sub???

Seroiusly all this "ohm" getting me confused...

 

[CJ_Clio89]

Just looking around at other amps and i know the loudest.com gear is highly rated on the site, but would this do....

i know its 2 channel and not a class d monoblock but, if i was to get the 2ohm version of the sub i want, it will be supplied with 1500 of power, using it to its full potential.

What do you think of that idea/ what amp would you use,

 

[Laura]

personally i owuldnt toutch that stuff with a barge pole

 

[CJ_Clio89]

Cheers, i think it might have been you who mentioned not to touch it before, i guess its cheap but you get what you pay for...

Will just get monoblocks then i reckon...
