If I connect (4) four ohm subwoofers to a four channel amp what is the total amount of ohms?

Question

If I hook up (4) 4 Ohm subwoofers to a 4 channel amp and I hook up 1 sub to each channel will the total amount of Ohms be 4 ohms or 16 Ohms?

Also, I have (4) 4 ohm Pioneer TSW302R subwoofers that are 150 watts rms and 800 watts peak, can I connect each sub to each channel of a Crunch P1400.4 amp that produces 175Wx4 @ 4ohms. (once again, I am not sure if this would be a total of 4 ohms or 16 ohms?)

Answer 1

to answer your question simply.... its a total of 4 ohms per channel.

Answer 2

i don't know much about car audio, but i know some electricity

in series (current goes through each, one after the other, before ground): 16 ohms

in parallel (current splits to go through all at the same time): 1 ohm. in a parallel curcuit, the total resistance is 1/(1/4+1/4+1/4+1/4)

Answer 3

I wouldn't do it.  You're not going to get good sound from a setup like that.  You need to get the right amplifier for the job.  

If you have four 4 ohm subs, your combined impedance will be 1 ohm if you wire them all in parallel.  Find yourself an amplifier that will put out at least 600 watts rms at 1 ohm and you'll be in good shape.

Answer 4

A. The total PER CHANNEL will be 4 Ohms.

B. You would be fine, but I wouldn't recommend turning your stereo up all the way as there is always a chance of blowing your speakers. Once again the Ohm rating is immaterial ( as stated in other answers) as long as you are only hooking up one speaker to each channel.

Now put two of those speakers on one channel and then you have TWICE the resistance or 8 ohms if they are hooked up in series. Hook them up in parallel, and you have HALF the resistance, or 2 Ohms.

Answer 5

Since your connecting a sub per channel, there is no total ohms as it's 4 ohm per channel.

You only total ohms when you have more than one speaker per channel.

Answer 6

One four ohm speaker to each channel is four ohms per channel. If the amp is rated at four ohms per channel that is fine. You do not calculate the ohms when it is just connected one speaker per channel. You only need to calculate if you have multiple speakers per channel.

Answer 7

You would only change the impedance (ohms rating) if you hooked several woofers up to the same channel. If they are four ohm channels, the 4 ohm woofers are perfect.
