what's the difference between 4 ohm stereo and 4 ohm mono?

[drpeeb 10+ year member]

the specs on my amp reads
50 x 4 @ 4 ohms STEREO

100 x 4 @ 2 ohms stereo

200 X 2 at 4 ohms bridged MONO

my question is what's the difference between 4 ohm mono and 4 ohm stereo?

None.

Edit: I think we have to know what the input options are.

Are you really under the impression that your stock radio's amplifier switches between mono and stereo based on power needs?

for that i really dont know, but u can test using a DMM an a single 1khz at 0 db, swiching the amp on mono and back to stereo.

i will try that one day.

You must be describing the antenna function which will switch to mono to compensate for a weak FM signal.

No dude... The aftermarket amp that he is trying to install, it has a setting for mono (factory radio), and stereo (aftermarket stereo). The factory amp doesnt need to switch for anything...

I dont know what antenna function you are talking about... My antenna doesnt have a switch //content.invisioncic.com/y282845/emoticons/confused.gif.e820e0216602db4765798ac39d28caa9.gif

If you don't have a stock stereo, always run your amp on stereo.

Mono only for stock radios.

I thought you set it to mono when you only had one radio in your car??

Usually on a amp a 4 ohm mono is used for a Sub and a 4 ohm stereo is used for front speakers and/or comps

a mono amp is 75+/- efficency while the stereo is 65+/- efficency.
thant means a mono amp will give more power than a stereo amp

*smacks head on table*

Why give advice when you're equally clueless?

i got this info from

4 ohm stereo. two channels. 4 ohm load each.

4 ohm mono, one channel (two channels bridged) = 2 channels at 2ohms each. sums left & right signal.

I used to have one of those old alpine amps. 4/3/2 channel amps. it's like a decepticon.
