three 4 ohm punch svc woofers

i have three 4 ohm punch svc woffers and i want to know if they can be wired togather in one box. and also would it sound right

thanks

You can wire 30 woofers together in one box and they can sound alright, just depends on how you wire them, the amp to run them and the design of the box. Share some more info on the subs, amp, box, vehicle.

Well, if they're 4-ohm single voice coil woofers, you're likely going to have problems, unless you can feed each sub its own separate channel of amplification.  I

f you wire them in series, you'll have a 12-ohm load.  Easy on the amplifier, and a nice high damping factor, but a waste of amplifier capability. 

If you wire them in parallel, you'll have a 1.3-Ohm load, which is a pretty strenuous load.  Most amplifiers won't handle this.  The ones that will may be prohibitively expensive.

You would wire three in series the same way you'd wire two in series. 

Positive amp terminal to first sub positive lead.

First sub negative lead to second sub positive lead.

Second sub negative lead to third sub positive lead.

Third Sub negaitve lead to amp negative terminal.

You end up with a 12-ohm load.  Nice damping factor, poor power output from the amplifier.

Exactly.  If you wired two of them in parallel to make a 2-ohm load, and then wired the third sub in series, you would end up with a 6-ohm load.  Unfortunately, as you assumed, the power wouldn't be divided evenly between the three subs.  Let's say you were pushing 10 amps of current through the whole combination.  When the current  gets to the paralleled pair, each sub would get 5 amps.  Power is current squared times impedence, so each sub would get 5 amps * 5 amps * 4 ohms =100 watts.  Then, the two 5 amp currents combine back again and the entire 10 amps flows through the third amp.  Using the same formula for power, the third sub gets 10 amps * 10 amps * 4 ohms=400 watts.  So it's even worse than you thought - the third sub actually gets four times as much power as either of the other two.

Obviously, that should read "Then, the two 5-amp currents combine back again and the entire 10 amps flows through the third SUB"

so in other words it wouldn't really work?

i have a 99 intrepid, kenwood 600 watt amp, three 4ohm punch woffers, and i haven't gotten the box yet

No, it won't work. If you want to use the gear you already have, the best combination would be to use two of the subs and your amplifier, assuming it's a stereo amp.
