I have 2 dual 4ohm subs. How do I wire them to get a 2 or 1 ohm load?

depends on the amp you have also....but if you run them in parallel +to+ and - to- then each sub will have an ohm impedance of 2.....know if you have a mono amp and connect both subs to the amp that will give you an impedance of 1 ohm.....but if you have a 2 channel amp then each channel will see 2 ohms....make sure the amp is 1ohm stable or you run the risk of ruining the amp.

the amp is a jbl 1200.1

that will do.....it'll see a 1ohm load.....give the amp enough air. It'll need it.

thanks, please run this by me again...how do I wire it for a one ohm load??

ok check it out..........on the subs what u want to do is wire the positive on voice coil 1 to the positive on voice coil 2....and do the same with the negative.......Wire negative on voice coil 1 to the negative on voice coil 2.....do the same with the other sub...

now on sub A connect a wire from the positive to the positive of the amp and aslo do the same with the negative ....now repeat the same thing with sub B....this will give you a 1ohm load.

now the jbl amp has inputs for two subs..it may look like a two channel amp but in reality its internally bridged, so its really one channel....they set it up that way so its easy to hook up.

can i make it a 2 ohm load with dual 4 ohm subs?

also, when i connect sub b to the amp, do i put the wires in the same input as sub A?

 

[rctecinc 10+ year member]

nope...thats the same problem i have....i wish i bought dual 2 ohm subs....but that amp can handle a 1 ohm load.....i have the same one....just keep it cool thats all.

you could but you don't have to....that amp has terminals for two separate subs...
