will a 2 channel amp run 4 speakers?

[moore19ca]

Interested in getting an amp for my car, just an upgrade over stock, but I heard that only 4 channel amps will run 4 speakers in the car, will 2 channel amps work?

Your better off just buying a 4 channel Amp

It depends on what the ohm rating is for the speakers, and what the amp will handle. For example, a 2-ohm stable amp- with four 4-ohm speakers- will work. But it is better to get a 4-channel amp, as gagt stated. Do you already have a 2-channel sitting in the closet or something?

the only reason you would need a 4 channel is if you want different crossover points for the front then the rear. If your gonna use the same crossover point u dont need a 4 channel.

what speakers are you planning on powering? you can use a 2 channel amp to power 4 speakers but you will loose your fade. I did it for a while until i could afford a second one.

My vote:
1. Use a 2-channel only with 2 speakers. Preferably front component speakers. Leave the rear speakers connected to the headunit - you don't really want/need to amp them anyway.
2. If you insist on amping all speakers, get a 4 channel amp.

Right... except the loss of the ability to control fading negates the improvement an amp would make. The more efficient speakers will be louder than the other set. I wouldn't recommend doing this.

agree'd except for one part. you do still have some fading options. If you connect both front speakers to one channel and both rear speakers to the other channel you will still have front and back fade, (but loose right left fade). so if you rear speakers do drown out the fronts you still have the option of fading it more to the front, thus fixing the issue. unless you want all your fading options then you are hooped. but like i said before this option is really only if you have no money and have a 2 channel amp laying around and get one super cheap. a 4 channel amp is better option or like said before just amp the fronts and leave the backs alone. What kind of speakers are you powering??

Hence why I stated a 4-channel would be better.

I would not amp the rear speakers, just the front.
