LoudBurp Posted August 26, 2011 Report Share Posted August 26, 2011 Use a DMM. Or know what coil config your subs are and how they are wired. Parallel cuts impedance in half, series doubles impedance. 2 4 ohm SVC subs can be wired to 2 or 8 ohms. Actually with series you add the resistances in the circuit and with parallel you add the reciprocal of the resistances and then take the reciprocal of the sum. It just so happens that typically you are using multiples of 2 of the same coil and coincidentally it doubles or is cut in half. You could actually wire a bunch of different coils together, in the same circuit, that have different impedances and it would work, not well but it would. Hypothetically if you had 4 coils (1 ohm,2 ohm,3 ohm, and 4 ohm) wired them all in parallel, you would have a total resistance of .48 ohm nominally. Now take the same coils and wire them in series, you would have 10 ohms. You would also think that each coils in these configurations would get equal power... THINK AGAIN. The power that each coil gets would be directly related to their impedance. Quote Best of Luck and Cheers! There is a point of diminishing returns on the amount of equipment installed, kinda like throwing money out a window. Link to comment Share on other sites More sharing options...

CHEVY4X4BLAZER Posted August 26, 2011 Report Share Posted August 26, 2011 I have 5 svc 4Ohm subs... Wired to 2 ohms. Do they all get the same amount of power? Quote Link to comment Share on other sites More sharing options...
BJD3 Posted August 26, 2011 Report Share Posted August 26, 2011 What everyone else is saying plus if you go to the12volt.com and go to the subwoofer wiring diagram it will show you ohm levels. Until you get more subwoofers than 5. In which case learning how to calculate impedence the "manual" way will come in handy. Not to mention if you're away from your computer and need to change your final impedance. Quote Anti Peel and Seal...lol You may be offended by the above.

UnderLoK Posted August 26, 2011 Report Share Posted August 26, 2011 (edited) I have 5 svc 4Ohm subs... Wired to 2 ohms. Do they all get the same amount of power? You have an odd number so if it's 2ohms you did something wrong. I would guess you broke them out into 2 sets each set at 8ohm then those together for 4ohm and then those four against the one that was left for 2ohm final. It should be wired to .8 Edited August 26, 2011 by UnderLoK Quote If at first you do not succeed, you are doing it wrong! -ARSCheck out my walled TBSS build over here4 Fi Team 18s on 2 Cactus K9 DS18 doors on 2 MBQ 1Ks, Vifa pillars on a STL4.500 Pioneer X8500 6 XS Power D7500, 1 3400S Second Skin 2 270a Mechman Alts Link to comment Share on other sites More sharing options...
vettedude102 Posted August 26, 2011 Report Share Posted August 26, 2011 True. Which I can go to it on my phone at any time/ I have learned somewhat about doing it in my head because of it.
