F1rtyfwe Posted October 3, 2010 Report Share Posted October 3, 2010 run em lower if your electrical is above par these amps shine when wired to .5 before rise Quote Link to comment Share on other sites More sharing options...
OrionStang Posted October 3, 2010 Author Report Share Posted October 3, 2010 If the DCR is 1.7, they are not 1.4 coils. . . . The resistance of the DMM leads is .3-.4 Quote SMD Super Seller My Feedback Thread Link to comment Share on other sites More sharing options...
sundownz Posted October 4, 2010 Report Share Posted October 4, 2010 Simply assume they are 2 ohms for this exercise. Wire to 4 ohm each woofer than all in parallel for 1.33 -- each amp will see 0.67 Quote - Jacob Fuller - Owner, Sundown Audio - Sundown Audio on FACEBOOK - Please DO NOT PM ME -- use my email address -- [email protected] Link to comment Share on other sites More sharing options...
OrionStang Posted October 4, 2010 Author Report Share Posted October 4, 2010 (edited) Simply assume they are 2 ohms for this exercise. Wire to 4 ohm each woofer than all in parallel for 1.33 -- each amp will see 0.67 Right, so if they are 1.4, the amps would see .46 each. Should be okay after rise, right? Edit: I think i'm finally catching on to the whole Ohm's Law thing.

Sanitarium Posted October 4, 2010 Report Share Posted October 4, 2010 Simply assume they are 2 ohms for this exercise. Wire to 4 ohm each woofer than all in parallel for 1.33 -- each amp will see 0.67 yeah i wouldn't have someone assume such things... ok here's your options, i'll make it easy for you. each coil is 1.4. 1.4 x 2 = 2.8 per speaker when wired in series 1.4 \ 2 - .7 per speaker when wired in paralell. ok now we treat each DVC sub as SVC subs with either 2.8 load or 0.7 load 0.7 x 3 = 2.1 0.7 / 3 = 0.233333 eww. 2.8 x 3 = 8.4 2.8 / 3 = 0.93333 ok now we got 4 optional loads to be split between 2 amps strapped. 2.1 / 2 = 1.05 0.2333 /2 = .. yeah we won't go there.. 8.4 / 2 = 4.2 not gonna see a lotta power here... 0.933333 / 2 = 0.4666666 we can call this 0.5 per amp.. SO there's 2 viable choices here. each sub in series with itself and parallel with the other 2 subs for a final load of 0.46666 per amp. or each sub parallel with itself and series with the other 2 subs for a final load of 1.05 per amp.

sundownz Posted October 4, 2010 Report Share Posted October 4, 2010 yeah i wouldn't have someone assume such things... You know... you are right... you probably know more about how to wire the amps than me Quote - Jacob Fuller - Owner, Sundown Audio - Sundown Audio on FACEBOOK - Please DO NOT PM ME -- use my email address -- [email protected] Link to comment Share on other sites More sharing options...
OrionStang Posted October 4, 2010 Author Report Share Posted October 4, 2010 yeah i wouldn't have someone assume such things... ok here's your options, i'll make it easy for you. Thats pretty much dummy proof. Thanks, i'm learning it. I think Jacob was just trying to make it easy for me. You know... you are right... you probably know more about how to wire the amps than me Thank you.

sundownz Posted October 4, 2010 Report Share Posted October 4, 2010 (edited) ... and since I was just joking above ... I will repeat A 1.4 DCR coil is 2 ohms nominal... you can assume it is a 2 ohm for wiring your amp. An amp designed for 1 ohm will handle a 0.7 DCR load -- it's taken into account. Same goes for wiring numerous woofers together... I've tested it and I've wired up a "few" of our amps over the years to 0.7 / 1.4 DCR woofers (1 ohm and 2 ohm nominal respectively).

bkolfo4 Posted October 4, 2010 Report Share Posted October 4, 2010 Man Sundownz, we posted the same thing. . .does not matter how many times it gets posted, people just don't understand the 1.4 ohms DCR vs. 2 ohms nominal AC impedance. . .
