heres the deal, i am planning on getting some ALUM10Q's for my s-10. these subs have dual 6ohm voice coils. 800 R.M.S. each. simple math tells me that the way to wire these subs  would be 3 of them parallel. so i need a amp capable of 800 watts x3 @1ohm on a single channel.  these seem to be kinda dificult to come by. audiobahn makes 2 one is huge but quite nice looking, the other is a rack mount. the rack mount will prolly have about 5 million functions that i dont know how to use but the other i think will be to large for the room i have.  any other options you can sugest?

So explain your "simple math" to me.  How many DVC 6-ohm subs are you running?

sory guess i dint explain that very well, there will be 3 subs 6ohm DVC wire each sub for a 3ohm load then wire the subs together in series should come up with a final load of 1ohm.....correct????   or is my simple math more like a 3 year old with a crayon saing lookie mommie, this is you----> drawing of dogie.....

If you think you're confused, imagine how you feel.   2400 watt x 1 @ 1ohm amp? -- posted image.

If you have three DVC 6-ohm subs, you would wire all six voice coils in parallel to the amp for a net one ohm load.  You say your speakers are 800 watts RMS, right?  If you are sure of this, then yes you would want a 2400 waytt @ 1ohm amp to max them out.  Audiobahn is not a good choice, IMO, since their ratings are out to lunch and their quality is marginal, especially when trying to run an amp at 1-ohm.  Look at something like a Cadence ZR9 or 10, JBL BPX2200.1, Orion 2500D or some other high power 1-ohm stable amp..

If you were to series/parallel the subs wouldn't you net a 3 ohm mono load? This would be a much easier load and allow you to have more amp choices. At 1 ohm your amp needs that much more current, generates that much more heat and sound that much worse. As far as Audiobahn, DYohn, hit the nail on the head. A few companies are doing the rack mount design, guess they haven't installed much. What a stupid concept!

Also, is your trucks electrical over par to supply the draw that this system will be pulling?

Im a little familier with S-10's, and i know that stock alt. isnt going to supply the juice.

I need quality equipment, feel free to donate.

Cadence ZRS10. 2500 watts at 1 ohm.
Look at www.usacaraudio.com

Or, why don't you run 3 voice coils in parallel (one from each woofer) and then do the same with the remaining three, for two 2 ohm channels? then you could spend around 1100 bux, get the monster 4KW digital amp from Eclipse, (stereo amp, and NOT bridgeable, but still 2000 watts per channel) and NEVER have a need for even one more watt of power... also the efficiency of digital is nice, means more power out for a given amount of power in... more efficient use of your MANDATORY HO alternator. It will become very important that you match you gains correctly, and your enclosure will HAVE TO BE ABSOLUTELY PERFECT, but this setup will ensure completely clean power at all listening levels, if overpowering a bit. (OK, OK!! overpowering 100 percent... overkill is my MINIMUM!) If you are worried about overpowering by 100 percent, then save a few bux, and buy the Eclipse Monoblock digital amp for 2000 watts, and wire your woofers in series-parallel for a 2 ohm load. Either way, you CANNOT go wrong with the digital amps from Eclipse... I have used both of them, the stereo amp is presently in my system, and I used the monoblock on a single Eclipse Ti 10... Like I said, overkill is my minimum.
It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

first i thought you had to set up Ohm loads at even numbers 8ohms (home sterio) 4/2/1 ohm (car audio)   dont remember where i herd this but ive always followed it. i dont even know if it was reliable info. i dont claim to be a pro at this but ive dont several low end installs (best buy specialz) for friends

someone mentioned wirng one voice coil one one sub to the left channel and the other to the right channel. ummm what would happen if the were two diffrent notes played. i know this example wouldnt apply to subs but youll get the idea.....two diffrent singers one on the left channel and one on the right. would there be any adverse effects on the driver?
