Learnin Posted May 28, 2012 Author Report Share Posted May 28, 2012 does your voice coil impendance have to match your overal load... like if you want to run a 1 ohm load you have to run 1 ohm coils? .5 ohm load = .5 ohm coils? Quote Link to comment Share on other sites More sharing options...
sprkn_ranger Posted May 28, 2012 Report Share Posted May 28, 2012 (edited) How you wire your sub is going to determine the final ohm load the amp sees. Let's say you have a sub that is a dual voice coil sub. Let's say that it is a D4. That means that each coil is a 4 ohm coil. If you wire them in parallel, that brings the impedance down to 2 ohms. If you wire it in series, that will increase the impedance to 8. So depending on how you wire it determines what ohm load you amp sees. The lower ohm load your amp sees, the more power your amp will give to the speaker, but it also requires more amperage from your electrical system. Read as much as you can from the sites linked above and then read it again till it really sinks in.

Crandis16 Posted May 28, 2012 Report Share Posted May 28, 2012 lol, check out crutchfield, they have some helpful wiring diagrams that I used to use to help learn about this stuff. http://www.crutchfield.com/learn/learningcenter/car/subwoofers_wiring.html It really is hard to explain until you have a basic understanding of ohms law and parallel and series circuits. Just read up a little on it and you'll do just fine when it comes to wiring techniques Quote My Red zx2 Build Log My Black zx2 Build Log My Red zx2 UBL Link to comment Share on other sites More sharing options...
Crandis16 Posted May 28, 2012 Report Share Posted May 28, 2012 (edited) Parallel wiring calculation: Rt=total resistance R1=resistance of first coil R2=resistance of second coil both coils happen to be the same resistance (+)..........(-) I...............I I___R1___I I...............I I___R2___I (1/Rt)=(1/R1)+(1/R2) and Series wiring... Rt=R1+R2 (+)------R1-------R2-----(-) Edit: ignore the periods in the parallel example... it didn't like me putting just spaces in there so it made it all squished together Edited May 28, 2012 by Crandis16 Quote My Red zx2 Build Log My Black zx2 Build Log My Red zx2 UBL Link to comment Share on other sites More sharing options...

bassface Posted May 28, 2012 Report Share Posted May 28, 2012 is their a book i can buy to learn this stuff... whats a d1? difference between parallel wiring and series? i need to do some research obviously lol If you have trouble there are videos on utube about series, paralel, and series paralel. They are actually pretty easy to follow, just make sure to test with an ohm meter. Quote Link to comment Share on other sites More sharing options...

Emmet Posted May 28, 2012 Report Share Posted May 28, 2012 I think tbh you're better off buying an electronic circuits book to learn, if you can learn to wire various components into circuits in various ways, no matter what scenario you're faced with you'll have no problems. Plus it's real handy knowing how electronics work when working with any systems, not just car audio. Helps avoid a lot of headaches.

There are many general rules like constant voltage throughout a parallel circuit and constant current through a series circuit. There's also stuff on capacitors.... you should never have to use capacitance when dealing with any of your systems I hope though lol. None of it is really difficult, it just takes some research really. I learned in class so I had it done the easy way Quote My Red zx2 Build Log My Black zx2 Build Log My Red zx2 UBL Link to comment Share on other sites More sharing options...
