wiring 3 subwoofers

Ok, I'm installing 3 subs in a friends car soon, he's got a mono amp and 3 4ohm SVC subwoofers. What would be the best wiring configuration for this? I usually dont have problems wiring subs but I've never done 3 SVC subs run to a single mono amp.

What's the amp?Support the12volt.com

its an 1100 watt Sony, one of those new ones. XM-D500X That one."Shiny chrome when used in conjunction with bikini models is particularly effective in inducing brain deficit disorder"

Hmm.  Well it SAYS it is 2-ohm stable, so you could try all three subs in parallel, which will get you a 1.33 ohm load.  MAYBE it will handle the load, but since it's a Sony product you may just create a molten hunk of plastic where the amp used to be.  The only other option with 3 SVC 4-ohm woofers is to series them for a 12 ohm load, but I'll bet your client won't like that since the amp will only push about 85 watts into 12 ohms.  Sorry, it's not a good match IMO.Support the12volt.com

yeah, tell me about it. What about doing a series/parralle configuration? Like wire... crap, let me just upload a picture for it to show u what I'm thinking (its probably a crazy idea though lol) my wack idea.... anyway, let me know if u think that would start break'n stuff or what"Shiny chrome when used in conjunction with bikini models is particularly effective in inducing brain deficit disorder"

That configuration will give you the 12 ohm load with the center woofer in reverse polarity.Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.

ahh crap. Ok, thanks stevdart. I'm gona wire them up tomarrow in parrallel to see if the amp kicks off. If it does I'll just tell him he needs a different amp, aint like he's an actual customer of mine, just a friend who bought this crap w/o consulting me. Anyway, thanks for the help fellas."Shiny chrome when used in conjunction with bikini models is particularly effective in inducing brain deficit disorder"

How about just installing two of the subs, that is if the power won't be too great using only two.  Then you can have a two ohm load.  He can then start looking for replacements, and get dual 2 or dual 4's.  Stick the third sub in the hole for looks, lol.Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.

if you wire two 4 ohm subs in series you get 8 ohms and then wire the 3rd one in parrallel with the two in series you get a 2.66 ohm load.i think it would work,but test it and see what it does.if i can't make it sound good,then it is just a piece of crap anyway

That would work as far as loading the amp, but not as far as listening to it as the single sub in parallel will get twice the power as the two is series, and you might as well only use two.  A far better suggestion is to use only two subs, or get a different amp, or try it in parallel and cross your fingers...
