dual voice coil 2ohm or 4ohm

[airtas 10+ year member]

i know im a newbie, probably get flamed for this

did a search

can someone break it down in retard terms

i have rockford dual 4ohm voice coil subs

they make the same model in 2ohm dual voice coil

what is the difference??

depens on what amp your running

The impedance of the voice coil is the only difference.

Welcome to the board, first go to http://www.bcae1.com and do some reading //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

now dont you get more power out of 2 ohms?

i have a 2channel amp

A dual 4ohm sub can be wired to 2 or 8ohms.

A dual 2ohm sub can be wired to 1 or 4ohms.

That is the only difference. They make them like that so you can better match your subs and amps. If you have a 2 channel amp and one sub, more than likely you will want a 4ohm final load bridged.

Yes, if your amp is stable to a 2 ohm load. Not all are.

The difference is the resistance the coil has. If you have access to a basic HS physics book get it and read up on ohms law and electricity along with some basic circuitry and you will completely understand this. Also, try a search for ohms law on yahoo/google and do soem reading there, Im sure you could find some good stuff.

what about 2 subs and a 2channel amp? they are dual 4 ohms voice coils

and you would determine that from the specs?

It would say on the box, did you read what I said???????????

according to tech support on sounddomain.com it is impossible to wire 40hm dual voice coil subs to a 2ohm impedandence, i thought you could?

As long as that amp is stabe at 2ohms x2 then you can wire each sub in to a 2ohm load on each channel.

so what are all the possible hook up options for

a 2channel amp

with two 4ohm dual voice coil subs?

ok, READ CAREFULLY.

A d4 sub can be wired to show 2 or 8ohms impeadance, with two of them you can get 1, 4 or 16ohms final impeadance. Usually, an amp will put out more power at lower impeadances, but if your amp is not stable at a certain impeadance, you CANNOT wire it there without the risk of destroying a perfectly good amp.

Look at the specs for your amp, it will say it is bridgable at a certain impeadance (probably 2 of 4ohms). You can tell this because it will say Xwatts rms @ Xohms bridged. If it says @ 4ohms bridged, then wire your subs to show a 4ohm load, not two and not 16.

Get it?

Most amps are stable at 2 ohms in stereo(one sub per channel), but not bridged. What you want to do is wire each sub in parallel, one per channel. That will give you xx watts x 2 @ 2 ohms. Check the box/manual for the amp to fill in the xx's.
