hi there
sorry dudes but i still didn't understand the ohme system ....
i need to know if i can feel or hear the differnce in using the Ohms and how can i notice that :
1 Ohme ?
2 Ohme ?
3 Ohme ?
and 4 Ohme ?
thanx alot

Ohms are like light bulbs in a way. they have a specific resistance and depending on how they are wired to each other, they behave differently.
BTW, you don't have to understand Ohm's law to wire up a system. Just tellus in detail what you have in subs and amp and we can walk you through the steps.
Make, Model #, single or dual voice coil subs?
Consider talking a few basic electronics courses in school if you can. It will really help you understand what these things are about.
I have yet to find a primer that explains electron therory in layman's terms. I wish they made a "Dummies guide to electronics" ttype book. Those are so helpful on other topics. But if you like, try readig through some of these topics:

PS You cannot feel, smell, hear or taste an ohm... but the results of an amp being wired properly for optimal power (to subs) can be felt because of the proper ohm load matching. Maximum power to sub(s).

I disagree.....
You wire an amp with the wrong ohm load, and you will smell an ohm................. Maybe many.

The best way I know of to understand ohms is to know what they are (duh, hehe). An ohm is simply a way to measure resistance. Resistance is defined as opposition to current flow. In layman's terms, resistance is a quantity which describes how difficult it is to push current through something. All things have a certain resistance. The skin on your hand for example varies from as low as several hundred ohms (if it's real sweaty) to several hundred thousand ohms (if it's real dry). As a side note, this is exactly why you don't want to have a water fight next to a bunch of exposed power lines. Your soaking wet hand will have a much lower resistance than would a dry version of your hand, and so it is easier for electricity to pass through it. Consequently, you run a much greater risk of being shocked (or even electrocuted!). In case this isn't helping, maybe I should change gears. Think of current flowing through a wire like traffic flowing down a freeway.
Scenario: Compare two freeways. One has 69 lanes, and one has but a single small lane. Now if you think of resistance as opposition to current flow (or in our case traffic flow), which freeway has a higher resistance? The small one will have a much greater "resistance" because it would be much more difficult to get the same amount of traffic (current) through it in the same amount of time. The 69 lane freeway would be much easier to move traffic on because there are more places for it to go.
So how does this compare to the ohm rating on a speaker? Well a speaker is like a roadblock on the freeway of your stereo system's electrical path. Power from your battery flows out of your amp, through the speaker, and then to ground (via the fat wire going to ground from the amp). So how big of a roadblock is a speaker? Well that is determined by the rating of the speaker and how it is connected. The bigger the ohm rating of the speaker, the bigger the roadblock it is. Things get more complicated when you start talking about multiple speakers and multiple voice coils for each speaker, but the same principle still applies. Please let me know if my rambling needs to be explained differently.

Well done Pinch! That was pretty good analogy... freeway and all...
ttocs: Now that I think about it, yep, you can smell the results of getting the wrong resistance to an amp... true, I stand corrected.

I bet if you put a lot of paper next to the amp, and used ttocs' method, you will most likely smell the ohms, and then feel them too. Would be very warm, and cause a lot of light.

LOL, I'd actually pay to see some poor dumb kid run off and do that, then come back here saying, "Screw you Tray! You owe me $$$$."
It'd have to get very hot for it to do that too.

Now... now, don't be getting goofy ideas here fellas... could torch your ride.
