4 ohm stereo vs 2ohm mono...what the ****?

[mamey69 10+ year member]

as title says what the difference between mono and stereo... I saw that spec in an A/B class mono amp... so I thougth its the same ****.. it is???

mono means "one", like a mono amp has only one channel. Stereo amps have a left and right channel. It is possible for a stereo amp to give 2 different signals to a left and right sub, while a mono amp gives the same signal to all the subs hooked up to it. Mono amps are usually for subs.

why would u want to bridge a 2 channel amp ? if you got the channels use em i say //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif BAH

There are a couple reasons:

1. You want to use a stereo amp for one sub

2. You have 8 ohms speakers and want to get the most available power out of the

amp

3. There are more, i just don't feel like thinking of them.

Using that logic, why would you want to bridge an amp period? You're still using the channels when you bridge....

Assuming the use of 2 subs, which one would be better? Stereo vs. mono, yada yada yada. All too confusing for me.

1. 500x2 at 2ohms

2. 750x1 at 4ohms

Wouldn't it be better to get 500 each instead of 375 each? But there's the whole 2ohm/4ohm factor that is beyond me.

Here's an easy idea for ya.

Say you have two 8 ohm subs, your amp is a 2 channel amp with power ratings of 100x2 @4 ohms, and 400x1@ 4 ohms.

Now, if you wired one 8 ohm sub to each channel that sub would only be getting 50 watts a piece RMS, now if you wired the two subs together(creating a 4 ohm load, 8(impedence per coil)/2(#of subs)=4 ohms) and then bridging the amp? That way each sub would be getting 200 watts RMS.

Does that help at all?

can someone break down the meaning of OHM please ? or a link or something

Why would you want to send 2 different signals to 2 different subs.?? Makes no sense. Its sort of like in home theater, you use one sub to handle all the low frequencies, not 2 seperate ones.

you could if you had 2 //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

people usually set each channel to the same setting *if available* usually it sends the same to each channel. it just matters how your stereos VCs add up. if you have 2 SVC subs and want to hook them up to a 2 channel amp you would only get a 4 ohm load per sub, if you bridge them not only does it combine the subs and split it to 2 homs ..... it splits again to 1ohm when you use both channels together on them.

if you had a mono amp ... it would only split the difference once b/c the speakers would gather the power from 2 dif channels at once ...... you basically buy your amp around what kinda subs you get

thanks for the input guys but this amp only has one channel!! so how can it be mono and stereo at the same time its sayas stable to 4ohm stereo and 2ohm mono... its just one channel so why is stereo and mono at the same time??????????

in reply to a reply put up on this post, im not sure about you guys, but i have songs that have left and right bass, decending the bass from one side to the other, plus, you have a nice size gain when you use multiple subs, atleast thats what i have heard off sites like, http://www.eatel.net/~amptech/elecdisc/caraudio.htm a very very useful guide to learning things about audio, electronics, and other great stuff!
