Default speaker ohm ratings ?

Can you run speakers rated at 2 ohms connected to an amp that is rated at 4 ohms? I have seen this combo on various bikes and was just wondering what the pros and cons are? Will this cause early speaker failure or amp problems?

You can, but the 2ohm speaker will draw more current from the apm, thus more watts to your speakers. With all that means is more heat and if the amp isn't designed to run at 2ohm it will "thermal" (shut down to overheating) at higher volumes.

Most amps will be rated 4ohm, but typically that's in a mono config. Running an amp 2ohm stereo is equal to 4ohm mono.

So I would double check your specs, it may be just fine. What type of amp is it? I'll be happy to research it for you and see if I can find the info to help you confirm.

I have the Hawg Wired 120w amp.DCS1202. I am looking for a good set of 6.5,s to run off this amp.

match the impedance of the speakers to the amp.

some amps are able to run 16,8,4,2 ohms others do not

an impedance imbalance can blow the amp- ouch $$

it's up to you to check the specs of your amp

2 ohm speakers are not as widely available in the market.

----------------------

if you amp is rated to run 4 ohms, you cam use 2 x 2 ohm speakers on each side to total 4 ohm load on the amp.

in which case you would wire amp + to speaker + of the first speaker, then

1st speaker- to 2nd speaker +

2nd speaker - to amp -

that is series wiring.

and that takes care of one side, and you could do the same on the other side

2 ohm speakers on a 4 ohm amp could damage the amp as a result of over heating. exception is if you use 2 speakers in series of 2 ohms on the same channel which will give you 4 ohms per channel.
