2 ohm speaker wiring

do you have to wire speaker to amp different for 2 ohm? im really confused lol.

my amp (jbl 75.2) is rated at 97 watts x 2 at 4 ohms or 145 watts x 2 at 2 ohms, now my speakers are 2 ohm, how do i wire them up? cos i thought you have to wire them different.... not got a clue though maybe im wrong tho, atm iv just put the - into the - and the + into the + but im sure iv read about running wires parralell or something for 2 ohm, oh i duno, help!

I'm guessing you've got Infinity/JBL speakers, right? You wire them exactly the same as 4Ohm speakers.

Its only different when you're running a dual voice coil subwoofer.

there infinity.


but why if they run 2 ohms dont they sound any louder than if i run a set of 4 ohm speakers on there?

They're not really 2 Ohm, closer to 3 Ohm actually so you won't hear much of a difference. Make sure you have the amplifier gain and HPF set properly.

Twice the volume needs four times the power, roughly.

So if Jays right about them being nearer 3, you're not going to get a huge increase.

Bigger amp more power FTW!

Loudness will also depend on the sensitivity of the speakers used.

What speakers are you trying to run at 2 ohm's if you have two then it is always possible it may not be practical for Mit and Trebble playing speakers. But if you are trying to run two subs then this can easily be done by connecting the polarites of the subs together and then one of those to the amp so you could bridge the two channels of the amp wich should give you 300w RMS.
Do a quick search on Goooooooogle on two ohm wiring and there is a ton of info out there.
