Default Component set impedance

Hey guys.....i have JL VR 650-CSi components hooked up to a fosgate 301s amplifier in my tC.....my question is: Is there any way to drop the impedance of both the left and right channels to 2 ohm?? Possibly via some type of small capacitors or resistors or something plugged in-line from the amp to the crossovers??? any help would be appreciated....

I've looked briefly for something like that and haven't found anything.

Any reason why? Just want more power out of the amp?

what does the 301s put out at 4 ohm stereo?

4 ohm stereo it's only 75watts per channel...which is plenty for the VR's.....i was just wanting to experiment mainly......

I know there are some people who build their own x-overs and stuff to set exact impedance and slopes....but I'm not farmiliar with any of these technicalities.....

Can the speakers go down to 2 ohm? Is the amp 2 ohm stable? If the speakers can't go down to 2 ohm or the amp isn't stable at 2 ohm I wouldn't reccomend doing this ... The only way really to safely break a speaker down to 2 ohm is by have dual voice coils ... If you only have 1 4 ohm Voice Coil you won't be able to go down to 2 ohm ... Most of you components are 4 ohm ... Why do you want to go down to 2 ohm?

Not true at all. If you were to wire another set of speakers in parallel to that amp, at the same frequency, you would have a 2 ohm load. But I think what you meant was, the only way to drop the load on a single set of speakers, would be with dual voice coils.

For the orignal poster, here are some good links:

well......the only solution I've figured out wouuld be to hook a 4 ohm resistor inline with the components......i was mainly asking the question out of curiosity......doubt I'll actually try it......

Connecting a resistor inline would be "in series". So a 4 ohm resistor would make the load 8 ohms if your speaker is 4 ohms. I don't think there is a way for you to add in a resistor decrease ohms.

Wire it in parallel. Cuts resistance in half. But, just the same, why?

Buy better equipment.

How would you wire one resistor in parallel to a speaker without shorting the circuit?

all a speaker is, is a resister basically. it wouldnt short anything. like wiring two speakers in parallell. same thing

Adding a 4 ohm resistor in parallel would drop the load at the amp to 2 ohms but your components would only get half the power that the amp puts out since the resistor would take half. That means if your amp doubles power output into 2 ohms you would net nothing but a dirtier signal. You'd be wasting your time essentially.

If you want 2 ohm speakers just buy some, Image Dynamics makes their chameleons in a 2 ohm model.
