Gotta quick sub to amp wiring question
 

Ok i gotta alpine amp thats

Alpine 3554 4ch amp. 50 watts x4 at 4 ohms

Now if i was to wire 1 10" to the amp that has a 4 ohm coil, how many watts would it see. Its going to b bridged, not wired to jus one strait channel

should be ~200

Is it a dual or single voice coil?

Its a 10" bazooka with single voice coil. The single coil is 4 ohms. The amp does 50x4 in 4 ohms. Im going to wire the first 2 channels bridged like it says on the amp. How many watts would this b

alrite thanks man!

if ur using a 4 channel amp u will get 100 of the bridged channel

how do you figure?

I was going to say the same thing, but I don't know much. The way I see it the sub can only get power from 2 of the channels which is 100 watts.

Ok so you have an amp that puts out 50w @4ohms.

Ohms law
P=V ²/R and V=IR

P=power, V=volts, R=resistance, I=current


We know that 50w=V²/4ohm or 200=V² or 14.1=V.

So now we know the Voltage we want to solve for the current across each channel. I=V/R or I=14.1/4 or I=3.53

So now that we know the current per channel we can plug it in to find out what the power output of combining two channels would be. P=I²R or P=7.06² * 4 or P=199.37 watts
