I just got new subs that say they are 4ohm. But i think my amp is only a 2 ohm will it work or do i need a new amp? Thanks!

 

It will work, but the subs will not kick as hard as using a 4ohm amp. It's always best to match the impedance, but using 4ohm subs with a 2ohm amp is quite safe. The other way round is a big no no though, for future reference.

 

Thanks!! For future reference what is a good 4 ohm amp that puts out 1200 watts?

 

To clear the confusion....

You can run your 4 ohm sub on your "2 ohm amp", because the 2 ohm rating is a minimum impedance that the sub can drive, safely.

Amplifiers don't have "impedance", that can drive certain loads though. Most class A/B 2 channel amps are rated to run loads from 2 ohm to 8 ohm per channel, which is 4 ohm to 16 ohm bridged, why the difference between stereo and bridged? because when you bridge an amp, each channel sees half the load, so you will most likely be running your amp at full potential anyway, this is difficult to say though, without knowing exactly what the amp is.

A mono amp that is rated to run a 2 ohm load, will only be running approximatley half the rated out put at 4 ohms, depending on design, there are some amps that have the same power output regardless of impedance, JL amps are designed this way, others may have the same output at 4 and 2 ohms, but might drop at higher impedances.

 

I think you created more confusion for the poor guy than you cleared up....

Sorry I can't name any amps for you, as the market in the US is a lot different to that of the UK and we don't have the same brands here.

 

first and foremost question should be what woofers? Are they dual voice coil or single voice coil?

If they are two DVC 4 ohm subs, you can find monoblock amps that will power into either a 4 ohm load, or 1 ohm load. Mostly widespread is the 1 ohm load, which you will run into a list of good amplifiers.

But preferred a class D amp on subs over the older traditional A/B amp.
