wiring configurations considering 3 10s and..
Hey...
hey
im thinking about different wiring configurations for my subs to decide what kinda amp to buy.. and i'm wondering if I wired 1 sub voice coils in series, and the other's in parallel..if they'd still get even amounts of power each. Or.. you could even mix subs too.. get one with 2 4 ohms and the other 2 with 2 2 ohms? Im getting 3 10 inch alpine type r's, but i dont know if i should go with 2 ohms or 4 ohms.. and i need an amp, and im looking at MTX's Thunder81000D Mono-Block Class D amp.. ( http://www.mtx.com/caraudio/products...nder81000d.cfm ).. what will i need for that amp?.. 2 + 2 ohms, or 4 + 4 ohms?
thanks..

If you haven't bought your woofers yet and do want to use 3 10 " subs ,get them in an 8 ohm version .parallel the wiring .this will give you approx 2.6 ohms . the MTX amp will have no problems with this load .

If you can find 6 ohm DVC subs, 3 of them will wire in parallel to 1 ohm. Since most good D class amps are made for low impedence, this may work as well.
This is the kind of setup I'm running.

Not anymore. Like many monoblocks today the MTX can only handle a 2 ohm minamum load. [/QUOTE
Really?
That's too bad. I do know that the Concept line makes many 1 ohm stable amplifiers but I shouldn't assume all brands would do the same. I guess I'm a little

Alot of manufactures found that an amplifier that produce the most power at 1 ohm was less efficient then one at 2 ohms and that their was a lerger amount of distortion created by the 1 ohm load.

In reply to the original post also - don't mix impedances, and don't mix different wiring for different subs.
Whatever you do, use identical subs, wired the same way. You're begging for trouble if you don't - I can't remember the exact details why, but it's highly recommended to keep all things the same.

THe reason you don't mix subs is simply becuse one or a pair will always pull more pwer then the others. Also subs voice coils impedance changes as it plays if those coils are different at all as they play one will pull more power then the other. Since the subs aren't the same you can also get cancelation.
If you use 2 4 ohm subs and a 8 ohm, lets say you parallel them all you'll get a total 1.6 ohm load. If you use a 500 watt amp the 2 4 ohm subs will each draw 200 watts each and the 8 will only draw 100. Of coarse as they play these values will be all over the damn place.
