Got a stupid question...I recently bought a JL 10W3v3-2 used (low on funds), not thinking when I got it, I was wanting a 4 0hm sub for a 250/1. I love the sq of my 500/1 running 2 10W3v3-2s in series @ 4 ohms.

Can I add some kind of resistor to make that sub 4 0hms?

Will the sq difference be noticeable enough to worry about it?

I already built a slot ported box for a 4 0hm, has for cf, and 4. more slot length.

Yes, you can add a resistor to change the impedence of your sub. I seriously doubt you will be able to hear the difference in sound quality with your ears.

However, you will hear that the subs output is roughly 3dB less then what it should be, and that the resistor gets stupid hot as it has to dissapate half of the power your amp is putting out.

So, to sum it up, no, you can't simply add a resistor, as you will need a very large resistor and you would waste the power of your amp. Get the right equipment and do it right!

Thanks for your help.

I'll just go with what I've got for now.(not too long) Just hope it doesn't shorten the life of the 250/1.

Read here...

It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

The JL slash series amplifiers use a tightly regulated power supply which means they produce about the same amount of power at all impedances it can handle. If you are worried about SQ then just series the voice coils to 8 ohms.
