Whats OHM mean and can you explain it to me

Question

and what makes bass louder?

The watts in a sub or the OHM?

Answer 1

The link below will have a good explanation of what an ohm is and why it is important in car audio.

The site has a lot of good information where you can learn a lot.  You should look at more topics on the site to help you understand car audio much better.

Good Luck!!!

Answer 2

Go learn physics and stop listening to rap. It kills your brain cells you delinquent!

Answer 3

ohms are a resistance to electricity which every amp needs inorder to work. the lower the ohms the better but there's a catch. the amp must be able to handle it(it may say 2 or 4ohm stable). the way in which you figure out ohms is how u wire your subs. most are 4 ohms, but if you wire them with another, then the ohms may change. just be careful when wiring and do more research to figure out how to wire. once you understand that its simple.

Answer 4

Ohm is how the speakers are measured (in electrical resistance). The higher ohm means less current (power) can get through).  So lower ohm means more power (louder). BUT you cannot just go as low as you want. Amps have the minimum Ohm is can handle.

The WATT is the total power that it can put out.

Good Luck...

Answer 5

All speakers produce a certain amount of resistance which is what we call "ohms". Think of it this way....Think of a water faucet.Open the faucet all the way...more water comes out.....slightly close the faucet and the water will flow slowly or trickle persay. So lets use the water as an example of the flow of electricity(voltage and/or amps).And the faucet's valve that controls the flow is the speakers ohms(resistance). A speaker at 1 ohm would represent the water faucet being opened or turn up at the maxium or high level which a large amount of water would be flowing.The large amount of water would also represent the amount of power/wattage.

Now a speaker that is 8 ohms would represent the valve turned down to a minimum level creating a smaller flow of water or "power" flowing .... Thus,lower ohms on your speakers will create more power to flow from an amp.

However ,when dealing with Electricity/amps/voltage/current it creates HEAT.This larger amount of power creates large amounts of heat.This is why amps have "FIN'S" or slats.An amps outer shell is called a "heatsink".Its designed to absorb and dissapate heat. So that being said...Eventually the heat will wear down the amp if its not kept fairly cool.The heat wears down the various electronic components on the circuit board,thus increasing the chances of damage. Hope this helps

A MORE COMPLICATED VERSION:

"An ohm is an electrcal resistance on an amp provided by the sub/speaker. How you load an amp determines the amount of power out. There is a trade off though, the lower the impedance (ohms) the more power is pushed as well as higher distortion and more heat is generated. The excessive heat will shorten the life of the amp. For best overall performance, it's far better to get a higher powered amp and load it with 4 ohms than a lower powered amp and force it to push more power with a lower impedance (2 or less ohms) load. The other trade off is price. An amp that will handle higher power at 4 ohm will be more expensive. You should always match up RMS (Root Mean Square) watts of Subs and amp per channel as well as final impedance's (ohms). The two main methods of sub wiring are parallel and series and any combination depending on the type of subwoofer (if it's a DVC[Dual Voice Coil]).
