SOURCE: Wiring options

Hello chino2g,

For 3 DVC 4 ohm subs wired to a 2 ohm stable amp, your best option would be to wire all of the sub voice coils in series (individual 8 ohm loads) and then parallel the three subs for a final load of 2.67 ohms. There's really no other configuration. Here's the wiring diagram:

Hope this helps.

SOURCE: I have a 12 inch ORION HCCA dvc, 4ohm sub. My

Halving the impedance will draw twice the current. You could technically get a 3 Db more power since the peak voltage will remain the same. BUT if the magnet structure is not intended to use that cone design, the magnet difference MAY not give you 2 ohms.

In fact, if the designed magnetic flux were smaller, you could wind up with a 1 ohm speaker.

trying to get that much power is really kind of silly as even 50 watts with efficient speakers will exceed safe levels of sound that will not cause damage to your ears.

As you push an amp up in power, usually distortion will increase as well.

Definitely a 4 ohm load.If you do 1 ohm,that will send 4 times the current to the sub and you may end up hearing $150 blow out.2 ohm uses twice the power as 4 ohm and is still alot considering the power formula.watts=amps x voltage however amps are determined by voltage divided by resistance. 12 v divided 4 ohms is only 3 amps. 12v
divided by a 1 ohm = 12 amps when you go to crank up the power by turning up the volume,that results in even less ohms and more power.lol.Just use 4.Good luck! Greg

We recently purchased the MS350 radios and are trying to use them handfree with the headsets. We plugged in the headsets, turned on the radios, but are unable to communicated back and forth using the VOX...


The three things which come to mind are:
1) Is the headset the VOX headset intended for the radio model? Sometimes the rings on the plug do not match the internal points of contact if it is not the intended headset. Not all headsets are VOX capable.
2) Is the headset plugged in all the way. (You mentioned plugging in and then turning on. This is good. You must always have the radio turned off when plugging or unplugging an audio device.)
3) Try pressing the PTT on the headset cord one time before switching the dip switch to VOX. (Assuming you have a headset with the small box in the line.)

Check your VOX/ iVOX settings. You will need VOX for using an audio device.

Lastly, if you continue to have difficulties, contact Motorola at the 800# provided in the user guide. They should be able to assist you.

Best regards.

Can we wire with 220 single phase


It should be all set for 220 volts, a 3 phase timer would be twice that size if they make one. Little things don't run on 3 phase power. Are you just running the lights with it? If so, you don't even need the 220, just one side of it will do, make sure you have a wire to the clock motor, should already be there, check it out, Hope this helps.

I have 2 12 inch kickers and have a solid box in my mustang. would it sound better if it was ported?


Kicker speakers always require very large boxes (you're looking at 12 cubic feet for both), when ported. Ported boxes are very sensitive to box size, port tuning etc, so it's probably best to leave it sealed, as they are far more leniant, and sealed boxes are usually 1/2 size of ported boxes. You would get less bass when ported than with sealed (because ported boxes must be bigger to match the sealed ones).

If you wish to experiment with the bass response of speakers, download winISD, and put your speakers in, see what size boxes give you what.

I have 2 1300w Sony Xpod 12'' speakers and want to make a box and get the best thump, or quality. help plz


the box is not hard to make its what you make it from and how you port the box for sound the port are use as a tuner the bigger the port dont make it sound good , for the best sound make your box with the subs faceing inside the box get you some 2in pvc pipe to use for your port cut 4 holes in the top off the box infront off the speakers cut your pipe about 3 in short from the bottom of the box , make the box 16"X16"X4' you need to make a bridge between the speakers you will cut 5 pec 4X16 then 2 pec 16x16 use glue and scews

Size of boxes


Wow you are in luck, I used to be an Audiobahn dealer. Designing sub enclosures is my fulltime job. So here you go.-
If you are looking for sound that is very smooth, and has a very low end shaking everything setting off car alarms. You will need a PORTED BOX that is 3 CUBIC FEET FOR EACH SUB WOOFER. It actually calls for 2.7cu.ft but after you add speaker displacement and bracing it should be at least 3 cu.ft. The port can be either round or square made of plastic or 3/4" wood respectively. My port suggestions are dependent on how much space you have. The shortest round port might make some noise (too much pressure!). So think about that first. Anyway the short port is 3" diameter and 15.5" long. The longer port is 4" in diameter and 28.25" long. The rectangular wood port can also be either (port measurements are inside diamensions) 3" w x 3" w x 18.5" long (short port) or 2 w x 10.5 h x 48' long. The second longer wood port is recommended most but will take up a lot of space. The fact that you have to subtract the port volume from the box makes for space issues in cars. Also the second wood port sounds better and won't make much wind noise, but takes up .75 cu.ft worth of space. So in plain english your box will have to have an internal volume of 3.75cu.ft. An example of this could be made of 3/4" thick MDF, have 1" x 1" internal bracing and measure (box dimensions are external and assumes the use of 3/4" MDF) 12" h x 18" w x 30" deep. The port is an integral part of the box fitting inside. I'm sorry I can't provide any drawings to make things easier. Now this box size is one that I ran through a computer program I use. So it is not the same as the manufactures recommendations. I will list those as well.
The second box is an example using a round short port and also uses 3/4" MDF, 1 x 1" bracing, the 3" dia x 15.5" long port, and measures 12" x 18" x 24" externally.
If space is an issue try checking out the information below. -I got it from Audiobahn-
If for some reason it doesn't show up or you need assistance let me know. Good luck and enjoy your new setup-I'm sure you'll be happily disturbing the peace soon!

I chatted with a Matrox guy, and confirmed my suspicion - your card is dead. Your best bet is to simply replace with an inexpensive card (BFG makes some nice Nvidia-based cards), and stick with new product, rather than refurbed.
