resistors to make 2ohm 4ohm

[CJW 10+ year member]

I am trying to find a way to make my re8 svc 4ohm so I can run it in my house. My amp only goes to 4ohm and the sub is 2ohm.

I was wondering if I could wire resistors in line to make it read 4ohm to the amp. If so what kind?

It will be seeing about 150rms

Any help is very appreciated. Thanks

You just said that the sub is 4 ohm SVC. How is that 2 ohm?

he wantes to make it 4ohm. the sub is 2 like he stated, i would not do anything with a resistor. i would get another 2omh 8". wire them in series to get your 4 ohm.

You will burn out the resistor. I dont know where you can get one to handle that kind of power. The biggest I have seen is like 10w. But with some research you may find something bigger.

the resistor will **** power also. so just dont use one

They make dummy resistors for this... There kinda expensive, and they still take half the power your amp puts out, and covert it to heat...

Do they work well?

And yes I mean to make my 2ohm sub 4 ohm

Its for a setup where I only want to run one. I have 2 more but I dont want to use them in this setup

Never, EVER use a resistor for this. Get another sub or amp.

Voice coils aren't resistors, they're inductors.....

yeah, thats just a bad idea

I have what you need, but it costs a lot more than an new re 8 would.

Get a different sub, or risk it on the amp.

Eh, Ill prolly just get a different amp for it or get an audioque 8

Thanks

4 of them in parallel then in series with the RE8...at the price of an RE 8 now you'd save 30 bucks.

Or buy a tang band 8

or sell the RE 8 and buy this for a little extra cash

Thoes are similar in output to the oldschool Adire Shiva's...so a 12" one of thoes would make a single RE 8's output look sissy.

even if u did put it inline with a sub, the ohm load might drop but you wont see all that power dedicated to the sub itself.. cuz if you have a resistor inline its going to see voltage drop which means it will use some current too so this would defeat the whole purpose... just cuz an amp puts out 1000 watts at 2 ohm doesnt mean a sub will recieve all 1000 watts to itself.. the power would be divided amongst the sub and the resisitor..

that SHOULD be obvious...the basics of Ohms law arent that hard.
